I used to prefer “Forumverse” as well. But people don’t seem to want to use it?

While “Threadiverse” seems to predate Meta’s Threads here on Lemmy, see e.g. szmer.info/post/349217 and this comment from Ada lemmy.blahaj.zone/comment/93840 from 2+ years ago. Tbf I did find a reference to Forumverse from 2 years ago as well, but then virtually nobody uses it again until essentially db0@lemmy.dbzer0.com rediscovers it a handful of months ago.

So “Threadiverse” has some history behind it, except then Meta ruined the association for many people. But… we here on Lemmy were using it first!!?
