Fediverse = all activity pub based platforms (Lemmy, Mastodon, Pixelfed, etc. )

Threadiverse = Reddit-like activity pub based platforms specifically (Lemmy, Piefed, mbin, etc)

The name came before Threads was a thing, I think, so just a bad coincidence.

Piefed definitely seems to be winning the alt-lemmy race currently. There are a lot of them in that thread too

I have legitimate disdain for the .world fediverse comm. It seems to exist as an outlet for liberal/reactionary devs to advertise their Lemmy competitors and push people there.

And they’re entirely consumed by the idea of growth even if that would mean shifting the dominant culture rightward, when the leftist bent of Lemmy is exactly why I use it. If I want Reddit, I can go to Reddit.
