I do think that bluesky has a ton of momentum right now and is a viable alternative. But the thing about microblogging sites is that if the specific people you want to follow aren't on them, there's not really a substitute. I know I've heard people say that, for example, a lot of japanese game developers are still primarily on twitter (I've never been a twitter/bsky enjoyer so I can't speak to it personally).

Not if you want to make a living of it. People that do commissions tell me this. It's just what it is.
