The most confusing part of flakes is that it isn’t the default, but sort of defacto is because so many use it (myself included). At this point I feel it should be the default. The installation process doesn’t use the flakes feature so it has to be worked around and it isn’t straight forward.
Nix(OS) has a case of expert user base that aren’t motivated enough to make it easier for those unfamiliar with the concepts to get going.
Nix makes more sense if you understand referential transparency and functional programming. Even then, how a lot of nix expressions are written is quite confusing with all the self-recursive overrides, functions that are somehow also sets etc.
The best documentation and tutorials are probably somewhere other than in the official ones (though official documentation is not bad). Nix Pills and the wiki, especially.
Learning Nix and NixOS was the best investment I’ve ever made for my computer use since switching to Linux a decade ago or so.
The barrier of entry is so high I don’t blame anyone for not making the leap but I wish more people could enjoy the benefits. All other distros bar GuixOS feel utterly archaic and clumsily designed by comparison.
Matrix or IRC are popular. Can also be XMPP or any other open protocol. Bridge to proprietary networks if necessary but a FOSS project should never rely on Discord. https://drewdevault.com/2021/12/28/Dont-use-Discord-for-FOSS.html
You can configure NixOS to have as little or as much as you want by setting the right options. Guix is much the same.
Arch also allows customising to a similar level but that’s less… configuring and more installing things and tweaking stuff here and there.
To find videos across several instances there is this (as official as it gets) search engine: https://sepiasearch.org/
This is a much less extreme example, but I still feel it illustrates the point:
I don’t think a 2h old comment with no upvotes (beside the auto-upvote for new comments) should place above an 8h old comment with 4 upvotes. Whether a 4h old comment with half the upvotes of an 8h old comment should place above the latter is more debatable.
I’d like to find an example with higher numbers in a 24h window but that’s hard to come by at this time.
Edit: another example:
