Try to ask your IT guy, maybe he'll know more about this!
In my opinion, it is really useless for anyone else.
If you really want to, you can host it yourself.
At least, IRC had open-source servers and clients but in my opinion, it's too old nowadays.
Also what do you mean by "That are always full and require invite" ?

I'll make a follow-up in more time (some months) and go in more details!
Edit: Correction published!
The problem was: in the AUR, lots of packages didn't built or launch, and even in the official repos, some packages were missing libraries or just not having the right versions.
I was tired of tinkering to get everything to work as I wanted.
One of the advantages is that packages just works on the contrary of the AUR where I had lots of problems for lots of packages that wouldn't just not build or work.
I see NixOS as an easy way to re-install easily my system when I get a new machine or just to sync easily packages between my laptop and desktop (so they almost have the same things installed on them).
As for servers, I don't really see the point of nix as usually, pre-made and preinstalled images are already deployed. I think I'll still stick with Debian and all the usual software such as Docker for this usage.
