the experience is quite a bit different from twitter. a good mastodon server has mods , admins, and a community who moderate.
the signal to noise ratio is significantly better—maybe a decent comparison would be to compare here (hn) and a default sub on reddit with very little moderation—sure, you _can_ find interesting gems of a dialogue on the little moderated reddit sub, but your odds are significantly higher of finding good conversations here on hn. very very different experience.
