There must be some demographic which cares. I've personally only seen people amused by it.
SA = Sturmabteilung (NSDAP paramilitary org)
NS = idk, probably NatSoc / National Socialist
So for general internet usage, I think it's fine. We're not modelling the internet after German customs after all.
I'm not sure we're better off.
But there are other webs out there, speaking many different languages and carrying many different customs. The beauty is that if you don't like US customs, you can usually find communities that are far away from US culture.
Using it as in a vanity domain like we do with .me or .io, on the other hand, will definitely look weird.
1) hmm, they have .kz as the TLD
2) apparently thats kazakhstan? TIL
3) kinda weird that they, not being from kazakhstan, would choose to have that as their TLD. Maybe they're using it with another meaning in mind.
3.5) Let's give them the benefit of the doubt but remain wary of potential secret nazis, as one has to, here.
