Lots of people will hate me for this take but the best part of Twitter was its recommendation algorithm specifically between 2018-2021ish. The ability for everyone to meme about the same thing in the span of a few hours was fantastic and hilarious. I generally didn't give a shit about following famous people and have only been on Twitter for the meme culture.
Nowadays the algorithm is TERRIBLE though. I personally can't see myself moving to mastodon because I don't care about individual people though.
