“I tried the fediverse and didn’t follow anyone and it sucked, so I stopped and went back to Twitter again.”
These people would have hated Twitter circa 2008 when it had pretty much exactly the same issue.
But that’s the point of social media: to find likeminded people with common interests. Somewhere along the line that changed into social media being a thing that tells you what you think, and what you should be liking.
That’s easy, but it’s mental refined sugar. It’s just incredibly crap for you.
If you want interesting, fun and stimulating stuff, follow interesting, fun and stimulating people.
