Why is there a new wiki? What is with nixos.wiki?
The old wiki at nixos.wiki has several problems:
Many components (mediawiki, php, icu) are severely outdated.
MediaWiki 1.29 (EOL 2018), now 1.35 (EOL 2023-12)
PHP 7.3.33 (EOL 2021-12)
ICU 64.2
Cloudflare DDOS protection makes wiki edits fail sometimes.
There is no WYSIWYG editor.
The wiki infrastructure, which was supposed to be made public after launch, never ended-up being made public Many components (mediawiki, php, icu) are severely outdated.

I suspect both of these are a bigger deal to the Nix community than perhaps to the average group.
