I think whatever social media paradigm that comes next is going to need to have identities decoupled from websites, which shows most clearly on mastodon where you have different locales with different customs, except instead of going to the leather bar to hang out, you have to, in many ways, bring your instance with you -- and not get the benefits of local-feed
mastodon isn't the only example, just the one it's most noticable on. But see also everywhere else -- every social media space killed community forums, because, well, people just didn't have the attention for that -- they had to use the other website for most of their posting, and everyone else was there too.
but by having it be along the lines of internet-locale-based but you're just your pseudonym, is probably the way forward. Too bad most of the work there was all squandered on cryptocurrency-adjacent things this past half decade
