I was on Twitter pretty early (I eschewed just about all other socmed platforms), and it was really very good before algorithmic delivery of content started.*
If there's no algorithm, there's no algorithm to game, and a lot of this awful goes away. See posts from those I choose to follow. Period. That's the way I'd like it again.
Personally, I'd suggest removing the 230 protections for companies that deliver content algorithmically: by doing so they're actively acting as publishers, not neutral hosts for the content of others.
*(the original sin at Twitter was 'breaking replies'. Closing the API, delivering content algorithmically, prohibiting alternate clients all further enshitified it. The Musk disaster is just a coda.)
