@jendle I just tried https://www.movetodon.org - it found 80 of the ~600 Twitter accounts I'm following, here on Mastodon, and I was able to follow all by tapping one button (or I could have scrolled through the list & chosen which accounts to follow, individually). Pretty cool! Oh & character limits on posts are set by your instance, i.e. mine (urbanists.social) is 500.
