There's no reason we have to go anywhere after Twitter. Global social networks like Twitter, Facebook, Tumblr, etc., didn't even exist 20 years ago. We're probably better off without them IMO. The best Twitter replacement may be nothing.
I'm just frankly sick and tired of all the posturing, virtue signalling, and other wasteful garbage I saw on there. Oh, and the massive upswing in antisemitism over the last month (started pre-Musk). That had something to do with it as well.
I think if any of these disappeared, or all of them, are people suddenly going to start finding more productive uses of their time? No, they're just going to find other time wasters.
I think switching to "less destructive" would be a big step up.
Anyone who has experienced a tiny forum (or subreddit, or whatever) going viral knows what I'm talking about. Most of the time that experience at the very least transforms the existing local subculture for the worse, and sometimes outright destroys it.
If everyone on current-day Twitter would move to Mastodon at once it would turn into current-day Twitter. Which is not why I'm on Mastodon.
EDIT: can whomever downvoted this tell me what exactly they disagree with here?
But, it wont be reddit nor discord. Maybe it will just be nothing.
And I don't mean just because Musk took over, although he's made some decisions already that make no sense to me. It's got issues. People WANT an alternative.
