I think we need to start referring to Lemmy, Kbin, and presumably the dozen or so other 'ActivityPub with a Reddit-like interface' projects which will inevitably pop up collectively because while they compete the dynamics of that competition are in theory quite different to what you'd expect with centralised platforms as I can interact with communities on Kbin just as well from my 'home' Lemmy instance.

I quite like the term 'Threadiverse' that's been going around lately.
