The one problem with this is that most of the content does seem to be pretty centered on only a couple instances (lemmy.world mostly, with some also scattered in beehaw.org, Lemmy.ml, and sh.itjust.works). If one of those goes down, especially lemmy.world, it will cripple this place pretty bad. Maybe if we one day get a way to backup or export user profiles and communities to other instances, but until then, I think this place has a centralization problem brewing as well.
