I'd rather have a moderated site replace Twitter at this point, even if it's run by Meta. My first choice is for an intuitive non-Meta alternative to rise to prominence, ideally in the fediverse, but I think Mastodon had its chance and its unintuitive nature was too challenging for a critical mass of lay people. It needs to be: sign up, start posting. Instead it's: sign up, choose your server. Huh? You're already losing people.

All this has already been covered but it has to be simple and intuitive and that's what Threads is offering and Mastodon isn't.
