Fascinating to me that more than a few answers are along the lines of "Fediverse is technical, so I say (Mastodon/Lemmy/social web/social media etc) instead"
I'm not a massive fan of the term "Fediverse", but I don't see it as a tech term, more as a corollary to "web". It's a space, with a name, with things in/on it (for me I mean, just my opinion).
Once this in-or-on poll is done I think I'll ask more generally what terms most people use with their offline social circles.
