Not a lot here yet. I'll try to get more on that as I find stuff.
A search engine that prioritizes text-heavy websites with older formating. Good for finding interesting corners of the internet that aren't SEO.
The blog for the creator of marginalia.nu. Would highly recommend, as they document things about the search engine's methodology there.
A collection of a shitton of resources for building and maintaining a website.
A collection of tutorials on how to create and host your own website. Mostly has tutorials for darknet protocols and non-HTTP protocols like Gemini and Gopher.

An indie game developer whose games have been really helpful in teaching me the basics of programming. Also makes really good solitare variants.
