His main point is that it is forced and artificial. One vague heuristic a lot of people consider is the value of a social network depends on its "weird" subcultures. I feel however everything is far more sanitized and corporate friendly now. I really can't imagine a fun, weird subculture forming on threads.
At the moment there is no discovery or privacy to speak of, just most popular thing at top. A smart thing to do could be topics or rooms since there's a whole other market to be captured there right now.
Yep, Twitter has many "weird subculture" communities where people make obscure references, have their own values and in-jokes, &c. It does feel like these newer platforms are so artificial and cleaned up, and just so right-on and politically correct.
