The interesting thing is Bluesky has 3rd party feed generators, and there exists one called "infrequent posters" or something similar and it's run by one of the devs, it shows your chronological feed filtered down to just the people who post the least often.

They also have a ton of other feeds like a discover feed, a bunch of 3rd party feeds for topics like astronomy, photography feeds, etc. And a "for you" feed where the feed generator looks at your public interactions to guess your interests. You can pick and choose, or just stay chronological only. Or create your own feeds!

They've just launched 3rd party moderation labeling services too and limited federation is active (they're testing how the moderation model will work in a federated network now before they open that up fully). They're making the whole thing modular so you can pick and choose hosts, feeds, moderation, etc, from different sources and switch any of them whenever. Really interesting experiment and it seems to be working quite well.

Still only a Twitter-ish feed in the official bluesky implementation, but I'd like to see a forum like fork using this model with content addressing and all. "Forkable" and movable forums would be possible in this model.
