Younger crowd might not understand but back in late 90s early 2000 it was rare to find quality content/tutorials that are beginner friendly. Beej's Guide was one of the best quality content back then and even after 20 years it still stand in the first place in the topics covered.
Isn't it still a bit rare? I mean, to get any valuable results, I have to run uBlacklist (a search engine results filter) with a fairly large set of filters.
Having a well-written tutorial on one page, with no monthly fees, licensing, SEO, or ads (and someone who actively responds to emails!)... that's still quite rare, at least in my experience.
