ultimately my issue with the fediverse is that it assumes the only problems with twitter were the people you might encounter there and not the whole structure of modern social media and the psychological effects of how it fronts engagement. it's not just things like an algorithmic timeline or whatever, it's how there are systems in place like pushing forth how many likes/shares a post gets and how that encourages behaviours in the same way other sites did
like, it's not like twitter started having problems when the algorithmic timeline was introduced. even things like quote tweets (which mastodon thankfully lacks) encouraged dunking for the reward of Number Go Up. a reward structure like that is always going to bring out the worst in people, which kinda explains a lot of how there's very much a circle jerk thing that goes on on a lot of instances I've seen. this weird, sneering, celebratory attitude when things go wrong somewhere else
it's really no wonder I keep bouncing off it, and it's because it's loads of the things I've come to despise from twitter and tumblr and the like but without any understanding that those things are actually problems
