The other comments explain this better than I could.
In short:
I can post the same message on Twitter and Mastodon and get a thoughtful comment on the latter vs. no engagement/shitpost on the former.
Twitter feels like a bunch of angry people screaming into the void, whereas Mastodon is like screaming in a small cave filled with friendly weirdos. I like that. Eventually you lower your voice and start chatting.
