Does anyone know of a well-maintained, knowledge-focused Mastodon instance, large enough to have interesting local content? Say, 20,000-50,000 users?

@pieist Eh, here?

I think you have to be a bit more precise. Most large science-related instances probably fit this criterium?

@trinsec

As trinsec points out, without further clarification... here... Are you asking for QOTO alternatives in general, or something that isnt exactly STEM based?
