The lemmyverse sounds perfect, but it ignores alternatives like kbin etc. It would be better if we didn't end up with the situation we have with Mastodon where people assume Mastodon is the fediverse.
So, what do we call this little niche in the fediverse?
Feddy? Feddit?
I think sticking with fediverse works, while Lemmy and Kbin can be referred to by name, or together as AP (ActivityPub) “voting forums” or “link aggregators” as a category.
