The quality here is far better with the exception of maybe some user generated text stories. Posts don't just get lost in a sea of posts. The users here may not be as many, but it appears to have more consistent engagement and far less people PM'ing me offering me Amazon gift cards for feet pics.
This really is a nice place. Even most engaged posts hardly get over 50 comments usually, but 48 of those comments are on topic, sane and unique even on a fandom community. Arguments are heated but mostly contribute at least some point of view rather than being rabid spoutings that either get upvoted (or awarded) to skies above or downvoted to hell unanimously.
We have way fewer posts, even fewer do in niche communities. However, the posts on the bigger communities are quite enough to pass the time. What we actually need is more people interacting with the seemingly dead niche communities of their fandoms and interests.
Big communities keep crossposting a lot of daily news or magazine-worth happenings, which kinda gets tiring after seeing the same post for the 5th time. Hiding crossposts per user settings would be nice to prevent the feeling of only same posts being posted for interested non-fediverse users.
