Lack of consensus between clients, which isn't bad at this stage in the game, and user experience. Also, people aren't used to curating their own content. I think people saying bitcoin maxis are gatekeeping is just a ridiculous cop out because I've never seen it.

I still heavily use Twitter but under my following tab. I've curated my following for diverse information and viewpoints. Many people just want an algo to do this because they just want something "that just works right away." the algo is the doomspiral not the users themselves. It's designed to keep you coming back and will show you content you interact with most, even if that content is negative political views you disagree with. You have to be smarter then the algo and not give in.
