And the feeling is... very different. There was lots about Twitter that subtly enraged me, like pop-sci Covid takes showing up in my algorithmic feed after I had extremely carefully curated my followers to only include actual scientists who knew what they were talking about. And it's also refreshing not to have all those ads. In general, I feel like you've got a lot of control of your Mastodon experience, if you curate your followers well, it can be quite good. I have rules of immediately "unfollow boosts of" anybody who posts viral "boost this if..." or bullshit polls, and that's cleaning up my feed as well.
I've also been followed by my first crypto account (so I might go to followers-need-approval), and have seen glimmers of the same kind of dumb drama you see on Twitter, but overall feel like I generally have the tools I need to keep all that in check. I was finding that Twitter was bad for my mental health, and took a bunch of breaks from it even when I was having generally positive interactions and finding good info. We'll see how this goes, especially as things scale.
