To be honest though, I’ve been in many weird enough places on Twitter that I can confidently say that Mastodon is really dull, quiet, and less diverse compared to there.
And like, from people I follow, most of the more interesting ones aren't even using Mastodon, but rather Pleroma, Miskkey, or some forks of those. It's a diverse network, not only in types of people, but also in types of software. I would suggest you explore it more after a month or so, after this twitter wave blows over and dies off once again, as there's certainly some very nice communities out there.
