Saying "Lemmy/Mbin/Piefed" is too long, just Lemmy is reductive, "Threadiverse" doesn't really roll off the tongue,we are only a subset of the Fediverse. What would you call us? Horrible names allowed
Seriously. Mastodon is just a huge monoculture, and you probably wouldn't be able to tell a user's instance from their comments for example. While forumverse (i'm going to use this now xd) instances feel very defined and not too hard to tell where users are from (except with general instances, that can get hard.
Isn't that a bit of a shame though? I mean the fact that there's so little interconnection between these platforms. I know culturally there isn't too much but also the threadiverse often doesn't federate properly or support the way the rest of the fediverse works.
