.org was always intended for miscellaneous sites that don’t fit anywhere else, I think that’s the most appropriate. I mainly remember this from back in “the day” but here’s a source I’ve just found to back me up: https://datatracker.ietf.org/doc/html/rfc1591
I’m not a big fan of the “new” generic TLDs like .world, they’re not part of my hill, I don’t really care what they’re used for but I think we could do without them. Most Lemmy instances should really be .org in my ideal scheme of things.
It should be yes, though to be fair Americans are the worst for doing this when it’s the other way round.
