I wonder if this isn't a matter of social network but amount of (problematic) ppl. I've seen the fediverse change that way. Fediverse still has good ppl, but include the wrong ones and you completely lose the vibe that was there only a few years ago.

Yep, this will be a big part of it, and will likely be how we get a bunch of sub-nostrs that will cater to all kinds of different tastes and people. One big social network doesn’t make much sense unless it’s loosely federated.
