Yes, I started it a very long time ago (most likely 1994 but that's before Wayback Machine, and I don't have my own archive). I should update the links on that page, but I've been focused more on my new site (http://www.redblobgames.com/), where I'm writing tutorials with interactive diagrams.
Longevity is a goal for my site so I try to focus on algorithms, design, and techniques, rather than specific platforms, languages, or code.
I came here to vote this article up. I didn't expect you to be posting here. I love your site. It has been an awesome resource and I have referenced it for other people multiple times.
I really enjoyed your piece on procedural terrain generation. It's so well written that it's the first thing I think of when I want to help people understand that concept.
I also really liked some of the work you did with the interactive diagrams, especially the article on modeling dice rolls.
The way you have made this information accessible is very impressive to me. You make me want to do the things you do for others.
How did that work out?
