Most people I follow have either stopped tweeting, or largely tweet about Elon. Even popular YouTubers I follow can’t shut up about twitter/Elon.
Maybe I’m providing your point by not seeing non-twitter tweets but it feels like Elon starved twitter of real discourse.
Now, most of these folks are non-mainstream street reporters, establishment-critical types and the like (who Musk has claims are "repressing" him). Most of these folks simply don't care about Elon and just want to geek out about electoral / activism. But I don't see almost any of their tweets in the timeline.
If I have to create a List to see all their updates, what's the point of a timeline? (note: when I tried to add a lot of people to a list, Twitter logged me out / locked my account until I did 2FA again - very antagonistic).
That's when I decided to leave and haven't gone back since. Mastodon is very quiet comparatively but doesn't smell of Musk.
I think this shows the power of fads, not algorithms.
1. Tweets about Ukraine have radically decreased 2. Elon posts increase even when you don't follow him.
I'm not saying it's intentional. It just shows the power of algorithms. They dictate what is and what is not news. Even small tweaks matter.
