Bluesky has all the things that made Twitter a cesspool: a small character limit (300 is still too small) and virality stats (likes/retweets). Its only saving grace right now is that it's itty bitty; if it ever achieved scale it would have the same core problems. Which is to say, if you're betting on ATProto, try a Bluesky w/o those things.
But, more to the point, this stuff is just Usenet where the users are the newsgroups. But that's not the basis for a community unless the user's famous. What you want is something like forums (Reddit) where people with common interests come together. Anything else is like, hyperindividualistic and isolating.
It occurred to me that "Twitter is Usenet where individual users are the topics" is peak Millennial. Dunno what I'm gonna do with that one.
