The site that comes to mind is Ian's Shoelace Website. The ultimate guide about shoelaces. The most impactful/important thing for me was Ian's Knot, the fastest and most correct way to tie a shoe. I discovered this website in the mid-2000s and have been using his method since. Anyway, it's a fun and comprehensive website about shoelaces. https://www.fieggen.com/shoelace/ianknot.htm

I love retro video games (and current games). And some badass implemented the rendering of several games and consoles in JavaScript just for fun, so that you can explore levels from many games right in your browser.

Note that I did say explore, not play. This website let's you fly the camera through the level like with a "no clip cheat" (hence the site name).

Niche hobby website from the 90s that's both really useful and still updated (somewhat) - the Parker pen penography. Look at all those pens! Genuinely the most useful source of info on the topic of old Parkers that isn't a big hefty coffee table book.

Drew's Script-O-Rama.

He's been running the site since 95. I've been visiting since 96 or 97. I even provided the hardcopy for the Big Lebowski shooting script which he posted a few months before the movie premiered.

Well, Lemmy...

Curbside Classic a nice hobbyist site about Classic cars and related subjects. I go there every day, has a lot of extremely informative (but very niche) content

When I I've exhausted my Subscribed (HOT) and All (Top 12 Hours) Lemmy feeds but still have the desire to scroll, I usually head over to Printables to look at 3D prints for a while... see what my printer will be doing for the next week. I really like the filtering options that model site has. Less often I'll do the same on MyMiniFactory
