Great!
Actually, I was thinking !nix would be the better primary candidate, since Nix is sort of the trunk of the ecosystem where NixOS is more of a sturdy branch. Or to use another metaphor, Nix is the umbrella that covers NixOS. However, I understand that the official domain is nixos.org so perhaps it’s more ergonomic to also use this namespace to contain all things Nix.
At any rate, surely it’s not worth splitting hairs over. I’ll let you choose whichever option you think is best and follow suit!
Ah, good call checking Reddit.
Not that I’m aware of, I think just a pinned post explaining that all future posts should be redirected to !NixOS, and an explainer in the description.
