Bluesky's issue is the Discover feed is not good. After a few days of activity, the suggestions are mostly random and nowhere close to the stuff I want. Twitter was very good - it makes sense because the graph is rich.
Lots of other feeds, though. Which I think is a cool feature. I follow a feed for theme I'm interested in, which is nicer than following people that post about lots of various things, not all which I'm interested in.
