There are multiple sites that support follower semantics over RSS. Feedland tracks subscriptions publicly, so you can see the blogs I read (https://feedland.com/?username=robalexdev), and who reads my blog (https://feedland.com/?feedurl=https%3A%2F%2Falexsci.com%2Fbl...).
I run another variant which collects OPML blogrolls via crawling, so you can find out who else likes your favorite blog and what else they recommend. Here's the page for Simon Willison's blog (https://blogroll-network.alexsci.com/discover/feed-a34ee2a88...). Thinking of RSS and blogrolls as a network feels much more resilient than blueskys Jetstream api endpoint.
Nothing to do with Bluesky services. There are many independent firehoses and relays. Here's a stream of standard.site blog posts coming in over a firehose hosted in Chennai. Every single one. No curator between me and the posts, and no work by me to crawl the whole network for them. https://pdsls.dev/jetstream?instance=wss%3A%2F%2Fchennai.fir...
Edit: ok there is an aggregator, the relay is scraping all of the PDSs out there to build the event stream. Notably this is not possible with RSS, where you need to build a large index with knowledge. PDSs request relays to crawl and that's that.
- Semantic HTML
- Web indexing services
In this case, it's mostly indexing and a little of the other two if you want to add social features. I despite ATProto with all my soul for taking a problem with such a simple and standard solution and totally obscuring it behind hundreds of layers of JSON, faux federated services, and technical jargon, all in service of creating an inferior version of Twitter. I guess it wouldn't be as sexy to offer a web indexing service instead.

You can add Reddit to that list, IPO is coming so better price out the third party apps we encouraged developers to build.
