Eh we all have our opinions although I feel Threadiverse rolls off the tongue better than forumiverse (or foriverse which I also dislike.)

Also the term predates Threads by a full year, but I refuse to let the term die because of that association.

I just prefer fediverse, because it refers to the common network of apps and services speaking the same language: activitypub. There's not really any such thing as the "threadiverse", because lemmy can talk to mastodon, friendica, peertube, discourse, gnusocial, plerome, wordpress, lotide...

A lot of these have communities just like lemmy, and choosing to layout comments flat vs in a tree, is entirely a UI consideration for many of them. So if the thing distinguishing "threadiverse" is just comment trees and communities, then a lot of fediverse services already have those.

Threadiverse vs Forumverse, not sure if there's a clear winner, I see both used interchangeably
