Scientists say X has lost its professional edge and Bluesky is taking its place

browsing bluesky for astronomy/astrophysics is fantastic stuff

only thing that seems to be missing from bluesky migration is athletes and that's probably because it cannot be monetized (well not easily)

Q6T46nT668w6i3m•1h ago
I bet they’ll follow the sports media and, my personal taste in sports media, has recently started to migrate (e.g., Defector editors and contributors).
AnotherGoodName•1h ago
X still appears above the fold in a special section on Google with custom previews.

Eg. searching 'Anthony Albanese Bluesky' for Australia's leader has a link to X, with custom integrated previews, above the Bluesky link of the PM despite the search explicitly stating Bluesky and despite the account posting to Bluesky.

It's hard for anyone to move over since the lack of engagement is rigged like this.

AnotherGoodName•1h ago
Btw if you set your browser default search to anything other than Google searching for people works much better. No customized bumping of X based links over other options when searching for people.

Duckduckgo and Bing put the bluesky link as #1 for the above. Seems straightforward to make the switch to me. If you haven't changed your browsers default search engine in the past 5 years now's a good time to do so. Much better results await.

tartuffe78•56m ago
I had to switch to DuckDuckGo for work, AI stuff was too annoying
cowpig•49m ago
kagi.com is a superior search engine compared with all three, to the point where I pay for a license for everyone in my company to use it.

The kagi assistant is also nice, only responding with AI when you add a question mark to your query, with the option of opening the query in a separate web search RAG w/the LLM of your choice

timeon•1h ago
Interesting, maybe it also shows quality of search. I know that these are barely relevant compared to google, but Bing, Ecosia, etc. are showing Bluesky link.
rdiddly•29m ago
We need the "scientists find X less useful" study for Google.

If only Bluesky could be as decentralised as the Fediverse [0] Trading one corporate overlord for another is not the smartest play.

wat10000•1h ago
The Twitter buyout should have made this obvious. When one company runs the whole thing, then some rich twat can wreck it on a whim, and there’s nothing you can do about it.
CamperBob2•59m ago
They aren't exactly equal evils... and if a federated replacement for Xitter were going to win, I think it already would have. Ease of use (and comprehensibility) are both pretty important in this business, and nobody seems to get that.
Al-Khwarizmi•56m ago
Opening an account on Mastodon was a pain even for me, a long-time Internet user and a nerd. I'm confronted with a choice of servers, but if I love cheese and golf, do I open my account on the cheese server or the golf server? What will be the disadvantages of choosing one over the other? Instant blocker right in the sign up process that made me actually give up several times. If it was like that for me, imagine how it could be for an average user.

The Fediverse will only be popular if someone releases a client that makes it as easy to use as X and Bluesky. Not sure if it's technically feasible (I don't know much about the innards of the protocol) but it doesn't seem to have happened at the moment.

archagon•53m ago
How is it a pain when you can just skip the server selection process and use mastodon.social like pretty much everyone else?
jsheard•53m ago
Doesn't pretty much everyone using the same instance pretty much defeat the point?
archagon•49m ago
We’re talking about the average user. They’re not going to be particularly passionate about federation. The point, to them, is to have a functioning Twitter-like social network.
krapp•45m ago
No, because the point is that not everyone is forced to use the same instance.

When I started on Mastodon I created an account for each instance I wanted to post to, which was slightly annoying but not much more complicated than signing up for different subreddits. Now I have my own hosted account and follow whomever I like from there. Of course you can follow any account from any account (if the admin hasn't blocked it.)

Al-Khwarizmi•49m ago
I see that now the website shows a simpler choice - join mastodon.social or choose another server. I don't think it was like that when I joined (maybe 2 or 3 years ago), you were just given a list of servers or a search and told to choose.

This is an improvement for average user onboarding - although if almost everyone clicks mastodon.social, you kind of lose the value of decentralization, right?

archagon•46m ago
I think there’s still value to having a long tail of independent instances, which can readily become more dominant if something happens to compromise the primary mastodon.social instance.
jghn•37m ago
This. I still don't understand why there's so much consternation over choosing a Mastodon server. It doesn't limit who you can follow. I suppose if you're the sort of person who actually likes seeing random content from people you don't explicitly follow it could matter, but that's not for me.
marssaxman•52m ago
I did sign up for a mastodon account, but then the server I used simply disappeared a couple of months later. I haven't worked up the motivation to bother doing it again.
SideburnsOfDoom•47m ago
> Trading one corporate overlord for another is not the smartest play.

Only if you expect to be there for ever even as they inevitably enshittify. Be under no illusion that although BlueSky is having its "first they are good to their users" phase now, it is temporary.

So make the most of it now while it's good, but be prepared to move on when that changes. Embracing impermanence is a smarter play. This is nothing new, thus passes all social media.

rdiddly•34m ago
Bluesky is a public benefit corp which at least nominally means they don't have to maximize shareholder value at the expense of everything else.

Decentralization is not a priority for most people. If anything, they actively want centralization, because it's easier. To get those people to decentralize, the solution will have to be dead easy and invisible. The AT Protocol being developed by the Bluesky people looks promising.

I don't work for Bluesky, I'm not on Bluesky, and I don't particularly care, but I found your comment unfair after reading about ATProto on HN literally yesterday.

mbStavola•13m ago
I wonder why the Fediverse metrics don't count Threads, the single largest AP instance by several orders of magnitude?
Q6T46nT668w6i3m•1h ago
In my experience, the change has been positive. I rarely see feuds on Bluesky and when they happen I find them especially embarrassing because it’s so unusual.

I stopped posting on Twitter around the acquisition but kept my account. When I do randomly check my timeline I’m genuinely disturbed by the disinformation and pseudo-science, especially in machine learning.

hdlothia•1h ago
It would be nice if scientists started being just scientists again instead of activists. Hopefully being cloistered on bluesky will bring the old vibes back
input_sh•1h ago
Scientists are allowed to have opinions outside of their work and share them.
hdlothia•1h ago
It is 100% allowed, I just don't think it's really helpful or beneficial for them or society

Especially when they try to lean on their status as scientists in order to try and have their opinions be more influential.

The cdc for example saying it's ok to disregard their previous guidance in order to protest for black lives matter is one of these credibility damaging moments that is hard to undo.

Braxton1980•1h ago
>Especially when they try to lean on their status as scientists in order to try and have their opinions be more influential.

How do they do that?

kelipso•1h ago
The “I am an expert, so listen to me drone about some political topic that’s vaguely related to my expertise” has been a thing for years now. And it’s usually some controversial thing that doesn’t have to do with science anyway.

In general, it makes scientists look really naive and makes them lose credibility when they talk about actual science.

wat10000•57m ago
Do they have any real influence? I’m about a million times more concerned about politicians who act like they have worthwhile opinions about science.
jonathanstrange•49m ago
Jordan Peterson comes to my mind. Although I have no respect for his opinions at all, I still think that, in the end, scientists have their political views should be allowed to talk about them. What they shouldn't be allowed is to insinuate that these views are anything other than their personal views. Hate speech and political extremism should also not be allowed because these damage the reputation of their university.

Other than that, I don't think it's right to tell them not to use their status to influence politics and society towards what they perceive as making the world better. On the contrary, they might have some duty to do just that.

AFAIK, the CDC itself made no such official statement, but many prominent figures in public health, including a former CDC director [0], said just that.

misiti3780•59m ago

wat10000•59m ago
So why is it beneficial for you to have and express political opinions but not them? Or are you deliberately doing something harmful here?
randyhaute•54m ago
Yeah, just a personal emotional opinion credibility was damaged.

Reliance on honorific language and HN account age have strong correlation.

Personally, as you are a private citizen none of us have an obligation to, it's better if you stay quiet and do not influence people who owe you nothing.

No joke, either. The average American anyway reads at a middle school level. Why assume you're any better? Have heard enough out of Americans. They can look at the credibility of their country and keep quiet for a minute.

archagon•50m ago
> The cdc for example saying it's ok to disregard their previous guidance in order to protest for black lives matter

That’s… not what they said? They said it was probably relatively safe to attend a protest because it was happening outdoors and Covid spread mostly through accumulated aerosols. It turned out to be good guidance: practically no one gets Covid that way unless a sick person is actively coughing on them.

3eb7988a1663•49m ago
So nobody is allowed to use their notoriety to amplify their posts?

No more athletes, musicians, artists, whatever. Everyone must be anonymous. Or is it strictly scientists who are not allowed to post if their profession is known?

sejje•1h ago
Reddit, pseudo-anonymously, is mostly where I do that, not where I've set up my professional presence.
omoikane•1h ago
Maybe the parent is lamenting how some people post a lot of interesting scientific content, but also a whole lot of other content on topics that they are not interested in, and unfortunately most social networks require following all aspects of a person and not just the parts that interest you.

Google+ had it right where you can follow just a community, and also you can selectively make your participation in certain communities visible in your public profile. I am not sure if Bluesky or Mastodon have something similar.

tjwebbnorfolk•55m ago
Ok but if I'm a radiologist opining about social media, I'm no longer practicing science. I'm just some guy with an opinion.

"Scientists say..." is becoming just another "studies show...". You can always find a scientist or a study or an "expert" to push whatever agenda the media outlet has.

Nothing about this is remotely scientific.

bell-cot•51m ago
> Scientists are allowed...

Literally true, perhaps. But have you ever noticed how reluctant non-scientist professionals are to voice opinions in their chosen fields? Lawyers preface everything with "not your lawyer", "not my area of practice...", "I'd have to look into the details of that case...", etc. Accountants similarly. Doctors similarly. Engineers similarly. Vs. it seems to be accepted practice for a nuclear physicist to speak ex cathedra about epidemiology, climatology, etc.

Q6T46nT668w6i3m•1h ago
What do you mean? Activism is an essential part of science but maybe I’m misunderstanding your use of “activist.”
glitchc•1h ago
No, it's not. Good science requires objective thinking and evidence-based reasoning. Claims must be proven, not accepted based on authority or prima facie evidence.
Braxton1980•1h ago
And what does this have to do with activism?
techblueberry•1h ago
This is also the definition of good activism.
kelipso•1h ago
There are no true activists anymore, what a tragedy.
techblueberry•50m ago
90% of activists probably do good boring unseen work, you only see the 10% who make a stink on social media or protest on the streets.
glitchc•37m ago
You might be confusing activists with volunteers. Those who donate their time and money are not necessarily vocal about their pet projects. I'm part of the latter and do not consider myself an activist.
glitchc•1h ago
Absolutely not. A scientist is expected to change their mind when new, counterfactual evidence is presented. Activists push for positions regardless of whether any evidence exists to support their position, and seem to maintain their position even when presented with counterfactual evidence. That is not science. We have a name for it: dogma.
miltonlost•58m ago
So Jonas Salk advocating for getting your child vaccinated against Polio wasn't a scientist? Just a dogmatist? Your definition of activism is foolish
techblueberry•52m ago
Wait a second, if you’re saying that this is not a feature of good activism, are you implying you are more convinced by activists who practice dogma over objective thinking?

What is a scientist to do when they discover a vaccine or cure for something; say fuck it who cares if we change behavior? Are you saying a good vaccine advocate is someone who ignores the underlying science and acts dogmatically?

It just feels like you want to demonize this action of activism for… why? Just because there are lots of bad activists? There are a lot of bad scientists as well, to be honest the view of “good scientist” and “bad activist” feels dogmatic.

glitchc•46m ago
I have yet to observe an activist practice objective thinking. That was the root of the argument. Activists sometimes do back the correct argument, but not because they are practising scientific reasoning. Most activists are swayed by rhetoric, a good story. That's an emotional response, not a logical one.

To answer your second point, science has a process for disseminating new findings. It's not perfect, but it works. Organizations that scientists work for do pay attention to those sources, discoveries do get patented and productionized. I encourage you to conduct some research: See how many people were talking about mRNA vaccines and gain-of-function research on social media before COVID vs after. The lack of social media coverage didn't affect the science or the scientists, who had spent the past decade conducting research on the subject.

I will maintain that Twitter/X/Bluesky are not part of the scientific process, nor should they be. These platforms do not encourage objective thought or reasoned arguments.

techblueberry•8m ago
Maybe the problem is with our funding model. Necessarily the whole grant system is based on being able to argue a narrative as to why your scientific inquiry deserves money. Combine that with a system that includes incentives towards or away from social values, and scientists are necessarily activists.

And then that’s just to get money in your specific direction, getting money in your general direction requires more broad activism.

matwood•1h ago
Unfortunately, social media or whatever has changed science communication. A scientist can do amazing science, have total evidence based reasoning and then be completely ignored because some quack tells a good story on Rogan.
glitchc•59m ago
That speaks more to society than science. We should not expect scientists to fix this problem. It's outside their domain.
kortilla•33m ago
That doesn’t matter and it’s not any different than 20 years ago. New findings could be published in medical journals that nobody in the public hears about and some quack on Howard Stern could spew to millions.
hdlothia•1h ago
I mean things like nature starting to make endorsements for president. Overly political for no reason.
parrellel•1h ago
They are planning on de-orbiting weather satellites because the administration doesn't believe in climate change. Nature was maybe on to something.
hdlothia•1h ago
https://www.nature.com/articles/s41562-023-01537-5. One study says the endorsement had little effect on voting intention but damaged credibility and perception of scientists.
DonHopkins•32m ago
Then why is it that YOU are working so hard to damage the credibility and perception of scientists?
miltonlost•1h ago
When one political party is explicitly anti-science in its goals and aims and actions (RFK, global warming as a hoax, anti-vaxx, COVID as a hoax), Nature endorsing the person who is pro-science isn't political; it's existential. This is not "no reason". It's just not the reason you like because for some reason.
hdlothia•1h ago
I feel like scientists should be explaining to us how the world is, and then other people should use those explanations to try and improve it.

Right now I feel like there are a scientists who would hide or discard results if they contradicted their advocacy beliefs,which is a dangerous place to be imo.

bArray•47m ago
You are correct.

It's because the left-wing that largely captures academia believes in the "rule of law" and more importantly, "policy by experts". Essentially when we boil it down, we're talking about an ideology that can justify anything if it's what "the science says". Of course, we are all aware that inconvenient studies can be prevented from running, inconvenient results can be discarded, and results themselves can be manipulated for the 'correct' result.

COVID was an example where unelected expert committees were given power to decide policy, and as a result schools were shut down at the detriment of education, hospitals were shut down at the detriment of the sick, and the economy was shut down at the detriment of the taxpayers. The COVID committees were singular issue task force: 'reduce COVID deaths by any means', and they achieved that task. A politician on the other hand is responsible for balancing several issues against one another.

Singular issue people/groups in general are quite dangerous and should be kept away from politics. We know, for example, that single issue AI is likely going to be a problem in the future, i.e. The Stamp Collecting Device [1] that destroys the world trying to achieve the singular issue of collecting stamps. Whilst the singular issue expert scientist is well meaning, a well-rounded politician should be considering the various trade-offs.

didibus•20m ago
What you say is just false. Politicians made and still make policies, that's how it works.
didibus•30m ago
That's how it works. I think people for some reason don't understand policy making. The CDC conducts research and studies, pulls data, performs analysis, and then provides guidance based on it.

It enacts no rules, laws, or regulations. That's done by policy makers who can listen to or ignore the guidance and data from the CDC at their discretion.

- Fire fighter

- Elementary school teacher

- Auto mechanic

- ER nurse

- Professor of Medieval History

roughly•50m ago
- Climate change

- School shootings

- Sure, they can shut up

- COVID

- Is this one serious?

tjwebbnorfolk•46m ago
Ah I see. So you want to use "science" to push particular political remedies to your pet issues.
roughly•35m ago
Oh I mean I don’t care if the teacher is for or against school shootings, I just find it interesting to have subject matter experts share their knowledge and give their opinions on things that impact their field. Some people just don’t take it well when those opinions don’t line up with their own on contentious topics.
bell-cot•7m ago
How is it "interesting" for an elementary school teacher to be against school shootings? I'd bet I can find some carpenters who are against smashing thumbs with hammers, but why bother?

Are you calling it "Activism" when someone shares the opinion of 99.9% of the population, and spends 0 time advocating for that opinion?

analog31•28m ago
Auto mechanic: Consumer advocacy, business regulation, labor issues, safety, etc.

Professor of Medieval history: Lots of political discourse makes claims about history or things like "the dark ages" that turn out to be mis-interpretations or false. Note that I have a friend in that field who often writes gentle corrections to false historical claims in online discourse.

umanwizard•55m ago
> Activism is an essential part of science

How so? It seems obvious that you can do science (that is: attempt to advance the understanding of how the natural world works) without being an activist for any cause.

tjwebbnorfolk•50m ago
The job of science is to discover facts and produce new knowledge from those facts. Activism is the marketing of an ideology. They couldn't be more opposite.

kortilla•40m ago
If you think either of those represent any meaningful portion of science you need to re-evaluate your understanding of science because it’s based on a layman’s perspective.

If you’re not actually involved in science you only see the scientists making news, which disproportionately selects for politically intersecting areas of research.

When I was working at a major US research university in the early 2000s, it was a big deal if the scientific publications got any mainstream press at all.

Countless papers push the boundaries of science in major journals and conferences every year and you never hear about them because they have no political implications and usually no immediate practical applications.

shakow•54m ago

That's true, but the other professions don't tend to be associated with (or clearly vindicate) the “above-the-crowd/holier-than-thou” attitude – and I say that as an ex-scientist, for the same reason (among others) as the poster above.

I doubt it. Most scientists are not activists. Yet, any scientist who achieves anything notable, has to be trained on how to deal with the media.

Science, and facts themselves, are political now.

outside1234•59m ago
Simply expressing the fact that climate change is happening is considered “activism” by some folks (and especially on X).

Asking them to “not be activists” is really a request for them to self police their speech in a way that fits their worldview.

This is not restricted to scientists by the way. Just look at the different response to how the NFL handled Charlie Kirk’s death with official moments of silence vs. Colin Kaepernick kneeing for police brutality. One is supported, one is suppressed.

Lack of self control or awareness. People make the mistake of thinking that because they are informed on one topic that happens to be political that their opinions on other political topics are relevant.

Why don't scientists publish anonymously? We already have double-blind peer review. This seems like such an obvious idea, there must be some issue.

Authors can still get reputation, recognition, and compensation for their papers, without people knowing who wrote what paper, via public/private keys and blockchain. Every time an author publishes a paper, they generate a new address and attach the public key to it. Judges send awards (NFTs) and compensation to the key without knowing who holds it, and if the same award type is given to multiple papers, authors can display it without anyone knowing which paper is theirs.

With LLMs even writing style can be erased (and as a side effect, the paper can be written in different formats for different audiences). Judges can use objective criteria so they can't be bribed without others noticing; in cases where the paper is an algorithm and the criteria is a formal proof, the "judge" can be a smart contract (in practice I think that would be a small minority of papers, but it would still be hard for a judge to nominate an undeserving paper while avoiding skeptics, because a deserving paper would match the not-fully-objective criteria according to a wide audience). Any other potential flaws?

How to force not only one, but three solutions into a non-existing problem. This must be a parody of cryto bros/AI bros, right.
armchairhacker•32m ago
Those may not be the solutions, but the problem certainly exists. I'm in academia and even I'll admit it has a lot of nepotism. People who are famous or infamous are identified despite peer-review (stylometry and subject) and the reviewers are biased for or against them. Also see comments like https://news.ycombinator.com/item?id=45396377#45396617: "It’s basically impossible to make a career as a scientist these days without constantly promoting yourself and your work unfortunately". If attaching your name to a paper becomes taboo, perhaps promotion will be less important, and if results can be judged algorithmically, definitely so.
ebiester•32m ago
1. It's a very small community and peer review is even hard. Think about it this way: what do you think two physicist colleagues talk about at a conference? How do you know who to talk to to collaborate on a problem? (Yes, people still talk voice about problems.)

2. Labs are specialized. You choose a lab to work at based on what they're working on. How are you going to choose where to spend your Ph.D or postdoc if you don't know what the lab is working on and how productive it is?

3. We are all still humans. We are wired to know the social systems around us. This would be an entire charade.

armchairhacker•26m ago
Ok, then scientists can form groups where they know each other, but publish anonymously outside those groups.

It doesn't solve all the issues, but it at least allows scientists to be "activists" (really just share their opinions like any other human) without affecting their credibility. Even if they're doxxed, they can eventually regain anonymity, because eventually other scientists with different views will publish papers on the same subject, and people can only distinguish who published what by its content.

Right now, scientists can share their opinions anonymously. This works well enough, except they can't share them in-person except to others they trust; and if they get doxxed, they can't remove their old posts from the name on their papers.

So firstly most scientists already aren't really activists in any meaningful way, it seems like you're implying most are on twitter/bluesky doing activism and the vast majority aren't really. Secondly I'm confused who people think should be able to be activists in a democracy? Scientists seem like a good candidate for people that should do activism in a healthy democracy.

Total activity across the entire site doesn't meaningfully affect users as long as the activity they actually care about is still there, "Bluesky's aggregate metrics are down" and "Bluesky is the best place to talk science" can both be true at the same time. The website you're reading right now has abysmal metrics compared to Facebook and TikTok, but that's not really the point, is it?
camel_Snake•41m ago
yep. This feels like a feature to me, not a bug. As a mostly reader/follower on these platforms I'm surprised when others compare their engagement metrics, rather than the quality of the engagement on these platforms. Obviously their goals and incentives are different than mine, but the more time I spend on the internet the more I value the smaller communities due to the correlation with quality and topical focus.

Aurornis•58m ago
As a light user who bounced around X, BlueSky, Mastodon, and Threads, I completely believe that scientists are weary of X. It’s increasingly toxic and driven by engagement bait posting (“shitposting” as they call it) where the loudest accounts continuously post provocative takes not because they believe it but because they know it will trigger their followers into debating it. Even the levels.io guy that everyone idolizes as the indie hacker hero is now posting a non-stop stream of factually inaccurate claims and taking swipes at contentious issues like burnout because he knows it gets people talking in his replies.

X seems to know this is a problem. They hired Nikita Bier who is posting claims that the algorithm is being improved to favor people sharing best in class knowledge every day, but the current meta appears to be posting controversial hot takes that are easily argued or debunked. Tricking your followers into fact checking you is a game in itself because it generates engagement and therefore extends reach. This is why some accounts are deliberate exaggerating facts or posting known misinformation now.

That said, I have a hard time believing everyone is migrating to BlueSky instead of simply leaving this type of social media. Bluesky feels relatively dead except for the few accounts playing the BlueSky meta game, which is largely about infighting and creating hyper cliques from what I see.

One account I follow went to BlueSky but then returned to X because he couldn’t stand it. He described BlueSky as the place to go if you wanted to be constantly attacked by people who 98% agree with you. My impression is that it’s a smaller pond where the people who were previously small fish on X see it as their opportunity to fight their way to the top of a smaller food chain. It just feels ugly and mean half the time. I’ve had to unfollow a lot of people on BlueSky who I previously enjoyed on X because they got sucked into the BlueSky toxicity competition and now they’re just taking swipes at other people on BlueSky all day instead of posting info I wanted to see.

Bluesky is filled with biased, politicized garbage from all corners.

It's only made me realize the 'professionals' are mostly political hacks that will abandon commonb sense and the truth, if it makes their political opponents look bad.

If you go against left-wing ideals on Bluesky, you will be censored or banned.

This doesn't bode well for actual science.

tptacek•48m ago
I don't understand how Bluesky is going to continue to exist past 2026, based on the sharply declining usage, their headcount, and the amount of funding they've taken.

It has apparent value propositions past the social network, but none of those use cases are visibly taking off and none of them appear to be monetizable. The social network itself is what will be evaluated when they go out for more funding. And I don't see how you can raise at all for a social network in 2026 with flat numbers, let alone the declining numbers Bluesky actually has.

I've been dual-wielding Twitter and Bluesky for about a year (after a year off Twitter where I was mostly Mastodon), and, anecdatally, we've hit a point where the engagement and volume of stuff I see in Bluesky is lower than what I was getting even on Mastodon. Earlier on, there was some truth to the idea that Twitter had a much larger audience, but you'd get better engagement on Bluesky. I now get better engagement on Twitter. I can see people I had followed into Bluesky moving back to Twitter.

I have no idea what's going to happen, but I'm curious to hear a coherent story about how Bluesky isn't cooked.

jghn•39m ago
What I've found is that most of the people I really want to follow are exclusively on bsky. BUT most of the people I'd prefer to casually follow either exclusively or mostly only posts on Twitter. And the 2nd group is a much larger pool than the first group.

I really dislike Mastodon so gave that up a while back. I know there are a few people I'd like to follow who only post there, but such is life.

packetlost•24m ago
I've found Bluesky does a really bad job at not showing me stuff I don't want to see. Furry p*rn on the "cute internet cats" feed? Yup. Heaps and heaps of political rage bait on the main discover feed? Yup.

I wanted to like BlueSky, but it's such a bizarre echo chamber of people who left Twitter for ideological reasons that it basically filters for people that I actively don't want to engage with.

Those types of people are still there on Twitter (mostly on the other side these days), but I don't see them because the algorithm filters them out.

Sharply declining usage? I don't see the stats to back that up on https://bsky.jazco.dev/stats

Usage has absolutely declined from peak switching periods where inevitibly some users won't stick around, but that's to be expected. Most stats seem to be leveling off (which isn't exactly stable growth either so the rest of your points stand).

tptacek•17m ago
Yeah, I think what you needed to do here is zoom out. That's a sharply declining chart.

I understand that as a Bluesky user the peak and dropoff doesn't hurt the experience. But investors are going to put money in with the expectation of a return and what they're going to look at are the derivatives of the adoption curve: how quickly is it gaining users, and is adoption accelerating?

Are you an insider? Where are the numbers?

how_long_can_bluesky_exists = f(usage, headcount, funding)

Three parameters and you supplied zero of them.

It does sound like you just randomly picked a number 2026 and proceeded to rant on how little engagement you received on Bluesky.

tptacek•19m ago
You can just Google these things. Nate Silver posted (grim looking) usage numbers --- followers and posters --- just a couple weeks ago. They very publicly raised a $15MM (priced) A round a year ago, after raising what I understood to be a comparable amount of seed funding. There was talk early this year of them raising again at a $700MM valuation, but I don't see a subsequent announcement that that happened.

You can generally take a headcount number and assign a fully loaded cost to it (say, $200k, conservatively) and just math it out. And of course that analysis assumes their infra expenditures round to zero.

So no, I'm not just making stuff up. I could be wrong! I feel like I was open about that.

epistasis•3m ago
Saying "you can google it" when the range of online information is massive is not a helpful thing to say. What numbers are you believing and why?

Nate Silver has basically zero juice on Bluesky, people go there to get away from that sort of "expert" that's got a huge profile already but is hard to escape if you are uninterested in his takes.

I mean he'll, take his own word on it, it's not the social network for him!

Most scientists don't have a professional profile on Twitter or Bluesky. It's the most self-aggrandizing ones who tend to do that.

The rest of us are just writing papers, presenting at conferences, collaborating with other research groups without any interest in putting it all out there on social media.

This whole X versus Bluesky thing is basically irrelevant. Neither of these platforms are good venues for dissemination of scientific research.
