I think you're assuming a know a lot more than I do. So I made an account and joined sh.itjust.works. I have a home feed, which I thought was just local stuff, but maybe also includes some common things with lemmy.world (including maybe this post itself?)
So far I've blocked one community and one user because there was some passive aggressive shit going and I got that scapegoat-vibe so common in reddit. Got some hope for Lemmy, because, yeah, I think people just get stupid when there's enough of them together in the same place.
And even though sh.itjust.works is tagged a FR-EN community, ain't seen a lick of french anywhere.
