I find myself posting more often on LinkedIn after the #Twitter crackdown. Especially for longer posts, it is useful. I know, LinkedIn is a centralized company as Twitter is (was?). However it's hard to rewrite some posts to shorter versions. At least for me.
If you want to connect there too - just hit the "connect" button.
@grobmeier You can search for instances which have a longer post limit? Some Mastodon servers are modified to have a bigger limit. But I also know that servers like ... I think Misskey or Calckey or Pleroma? have a bigger limit by default.
@grobmeier 500 characters is a vanilla Mastodon standard. ActivityPub can handle much bigger posts as the non-Mastodon instances already have shown. ;)
The server I'm on, for example, can handle 65k characters. Not that I never needed that much, but hey the option is there! ;)
