wait, i don’t really see how this is much more expensive than storing PDS writes…? is the architecture for following feeds not just
- watch for posts
- find all followers of its author
- append a reference to the post to that follower’s feed
you already need to do (1), (2) is not terrible so long as you can build some sort of index from author->followers, and (3) is well understood as a problem enough that it can’t possibly be all that slow … where does the complexity lie?
Scale. There are lots of people with tens of thousands of followers who post a lot. And people really want to find out about new posts quickly. It's a many-to-many high throughput low latency write delivery problem. And it's the only one: everything else bluesky does is either many-to-few, few-to-many, low throughput, or high-latency, and can thus be way cheaper to scale.

This is my favorite thing about atproto too, and it really bummed me out when I learned that Tangled only pushes pull request records, they don't ingest them and turn third-party-authored pull request records into commits on new branches. I was so looking forward to hooking my automated code refactoring tools up to a PDS.
I chatted with one of the devs though and they stated it's on their roadmap, so that's something. I really think people haven't grasped what's possible yet.

Chubby cuddlebot Lemma!
Honestly, I think Tap (https://docs.bsky.app/blog/introducing-tap) might be a good way to implement following feeds at a lower per-user cost, but that would still likely have a somewhat heavy cost.
The tricky bit is you can't just limit Tap to ingesting only the repos of accounts in your PDS, you have to ingest the accounts of anyone that someone in your PDS follows. With even just a few dozen users that can quickly become thousands or tens of thousands of accounts.Loading more comments...
