More Mastodon $0.02:
Con – Interface (especially on the web) seems a bit clunky. Hard to describe (also experienced in mobile apps so it's not JUST the UI). I see live tweeting more natural vs live… tooting.
Con – Some scaling concerns, more on that maybe later.
Pro – No quote w/ boosts. I think it might be a good change not to have in-your-face hot takes.
Pro – No "tweetstorms" or big 🧵 which were mostly annoying on #twitter.
Again IMO Mastodon isn't the solution but part of the answer.
