Hmm, really nobody?
- Russian (well, also French but it is probably covered by people who do less mistakes per line than me)
- Happy to answer Nix/Nixpkgs and easy NixOS questions
Maybe mix? We could have a new-language-introduction category, so that a language subcommunity can just assert itself into existence without anyone monitoring the profiles? (Noticing that an introduction thread gets to three participants and creating a new category and moving the introduction thread there sounds like less effort than noticing that there are many people specifying the same language in the profiles)
Strictly speaking, the question as stated also includes the users who can tolerate reading technical English, but cannot easily write in English (I know such people have to exist, I have such a situation with German and probably Danish. I am obviously useless in that context as there are enough native German speakers here; and an average person in Denmark between 18 and 50 has better English than me)
