@rks Mastodon is really just a software. The community using it that I know of is mostly leftish, but I don't know of a survey about it.
Pleroma people seem a bit more various maybe... but really, again, they are just softwares, I still don't know how comes this difference is there.
In qoto as I experienced is a mix of ideas living together in a surprisingly peaceful way, so far
@rks Sure thing, report back ;)
@arteteco Thanks for your answer. Let me go through the experience and let you know what I feel. :)
