@chpietsch @liaizon easy, we will see which lasts... I think fediverse has a nicer rhythm than fediversum, and often its the tone that makes names last, not correctness of any kind.
And for the födiverse - Föderation is not a common term in german, mainly exists in political state organisation. Might not be the context to highlight. (And in swiss german Födi is a diminuitiv for arse.)
