I'm extremely confident that at the very minimum Lemmy will be a nice little hangout spot, but it's seeming like it's going to be far more than that from what i've seen so far. It really is unique in that different types of shittiness is isolated within instances which means people will converge where they should be and problem groups will naturally DNI with each other leading to minimum conflict in the long term.

What really makes lemmy special is its true freedom of speech approach. And actual freedom of speech, not just nazis talking over marginalized people or single individuals controlling the conversation through their star power alone. You can make a random post, good, or bad, doesn't matter, and you'll actually be able to get organic traffic on it. I mean for god sake I made a crappy joke about cutting the mold off of cheese and growing marshmallows on trees and it got the attention that it deserved (which, to be fair, wasn't much)

Mastodon barely anyone will see you unless you already have a following, and that sucks. You don't really have to worry about that here.
