tl;dr Engineer discovers that sales & marketing are real jobs. Calling it “content creation” or “influencers” are just another way of minimizing a side of business development that scares you. Thanks for the story, it was an enjoyable read!
pixl97•1h ago
Marketing is a real job in the same way both pharmacists and drug dealers are both real jobs. Its really easy for marketing to go from providing a useful product to using dark patterns like rage bait to peddle the equivalent of drugs to the masses. Marketing gets a bad name for a reason.
limflick•1h ago
I share your aversion to modern marketing tactics, but by your logic, programmers that develop the addictive social media algorithms are the meth cooks. Everyone is complicit. Modern day "tech bros" get a significantly worse rep than marketing folks these days. No use in participating in this blame game.
SeanAnderson•1h ago
I mean that kind of tracks? I had to take a computer science ethics course in college. It mainly focused on stuff like the Therac-25 case study, but I could easily see a more modern version of the course covering social media algorithms.

I wonder if marketing courses also have an ethics component taught in them?

A good example of bad that can happen but damn is that just plain lazy.

More recent examples are surely more relevant and would generated more discussion.

I’ve been working on promoting my seating chart app for teachers, Shuffle Buddy, on social media. I had a 1M view pop on TikTok when I first launched and have now been clawing along to try for continued engagement.

It’s reassuring to know that social media posts are hard for everyone and that it isn’t supposed to be easy. I keep looking for ways to create content that is genuinely beneficial to teachers and also convinces them to try my app, but it’s hard.

wahnfrieden•1h ago
As a solopreneur I'm dreading the gutting of US TikTok... Things are going to get much harder for organic promotion if there's a separate US app under a non-TikTok name that only Americans can use.

You can look into https://sideshiftjobs.com or https://playkit.xyz for scaling organic posting btw (unaffiliated).

Personally I just message a lot of people directly myself and get lucky with friendly responses because creators like my apps enough that they use it themselves (edtech market makes this easier as the apps are genuinely and wholesomely bettering). Then I convince them to start new accounts focused on my app promo, in addition to less frequent commissioned promo on their main accounts.

For doing it yourself you need to get multiple devices and multiple accounts going, there are tools to help with that too. You can also post the UGC content that you pay others to produce for you, onto your own accounts. It's too difficult to consistently go viral without more frequent rolls of the dice. Focusing on a single branded account made more sense before current social media algos which don't care about your followers and won't even show it to them if the content isn't engaging enough to go viral beyond your following.

“Organic”

The post screenshots in those links are… uh.. hey I look forward to all of the free time everyone will have to do more productive things than “organically” shill for attention on behalf of commercial interests.

wahnfrieden•1h ago
It's just an industry term with a particular meaning. You don't need to rage at me about people getting paid for doing ad work because you don't like the jargon and don't like marketing.

People who do UGC work get paid enough to not have to work full-time if they don't want to, giving them more time for other things in life than most jobs. Typical jobs care more about exclusivity over your entire working day than the value of your output (hence why we have more of a "laborer" market than a "labor" market), let alone sharing that value back to you as is typical with UGC contracts. It's disappointing to see that kind of elitism here.

edit:

When you pay for ads/boosted content instead, all contemporary platforms have tried hard to make the paid ads look convincingly like “organic” content for long enough for the content’s hook to land - just look at X, Reddit, TT etc.

At least with “organic” promo, established accounts have a reputation to preserve or foster when they choose what promo work aligns with their audience and their values. As a consumer I can usually evaluate how much to trust a creator too by how scrupulously they choose their promo.

With paid ads I know I am just seeing it because they were the top bidder for my attention and that the only reputation protection from the platform is to avoid particularly criminal or other extreme content.

jondwillis•54m ago
Not raging at you, the term is newspeak, obfuscatory, slapped on top of antisocial behavior.

It’s better that profits are shared than fixed. But that doesn’t change the underlying system and incentives towards dishonesty.

klabb3•24m ago
100% agree. Plus ”organic” is an important term that has real meaning when you try to grow a product. Diluting it with paid advertisement just makes it harder to communicate clearly. Plus we already have a word for it, paid sponsorship.

I’m surprised the owner of Lagree didn’t sue you for the name of the app, he’s notorious for that. I also recommend hiring smaller creators, they can be amazing if it’s the right person

> Build it and they will come is a fallacy. You have to tell people about the damn thing.

Great lesson for engineering types

righthand•53m ago
I think the hidden lesson in Field of Dreams is that “they will come” happens because of word of mouth. Shoeless Joe Jackson tells the other dead baseball players to come hang out. The townsfolk tell about baseball field to save the farm.

But really “build it and they will come” in product development is pitched as if “they will come” because they are searching for it. Which is not really true if people don’t know your thing exists.

spike021•1h ago
I recently made a small game for iOS/macOS and basically every non-development part of the process between setting up the App Store stuff and trying to promote it have been a lot more work than I expected. Not even including the game design, which is really separate from the actual game development.

Have you noticed the different roles that make up successful small businesses? You must anticipate and learn to wear several hats in turn if you're doing it alone
spike021•46m ago
It's one of those things where I intuitively understand the roles when it comes to my normal job, but in doing this as a side project I foolishly thought it'd be more straightforward.
wahnfrieden•40m ago
We get used to peers across different roles doing their work for us and mostly unseen, at day jobs

TL;DR if you don't know who Sebastian Lagree is (my LA gf said "the pilates guy?") then don't read this.
ricardobeat•56m ago
For anyone also wondering, Lagree seems to be a high-intensity workout system derived from pilates, and "Sebastian" is the inventor/guru.

As a solo/indie dev who's currently early in building a product, I've been keeping a journal of "ideas" for content in a txt file in the codebase as I hate context switching and want to build this up before I get to it.

Here's what I've done:

- At the top of the file I've listed my audience, 3 personas

- My content has to be useful to one of those

- If I see an interesting post/take on social media I hold the link and write an idea for my own spin/take (takes 30 seconds) - log it

- If I have a problem/issue that I resolve that would be useful to my audience - log it

- If I have a key product/design/UX choice that took some time to think through - log it

- If something takes me much longer than I thought because there's more to it (iceberge effect) - log it

I've been doing this for about 6 weeks now and I've got 100 ideas for pieces of content.

One of the best pieces of advice I read is that when you're solo, many times people/community rally around you. You are the product too so you have to share what you're doing, it's interesting to many, not just your customers. They care about the advice you give, the input you have, the way you build things. You are a subject matter expert in this domain, so you should structure your content with this in mind.
