So far, mainly from this post bc the poll has such a small sample size, the term that seems vastly preferred is Threadiverse. Bc of its history, and how people have already been calling it that. Sort this post by Hot to see what I mean.

I don’t think Forumverse is “bad”, plus as you say it better represents the new additions of nodebb and flarum. Although that term would be swimming against the tide of people that have been using Threadiverse all this time and seem to not want to switch (possibly bc I did not explain the situation well, especially the clarification about the term Fediverse already existing, and now how the situation is a bit different wrt nodebb and flarum).

Ofc this is all just on a Sunday -> there is still lots of room for things to happen in the next coming days, to see how these results may shift:-).
