I think the community matters a lot more than the instance. Hexbear has a bunch of coping bubble communities but they keep posting the same low-quality comments, so that’s probably why the threshold of 20 comments is so high. Another example, I make posts to my own blog community !dginovker_blog@lemmy.ml, but there’s no subscribers so there’s never gonna be any comments.

Basically I’m saying you should do this same analysis across a sample of random communities ^^
