Stumbling into REST

I stumbled into REST accidentally about 1 month ago. Since then, I've learned to try (at least) to make the URLs more beautiful and this simplifying the sites that I create. Here are some resources I've found to be quite useful:

1) DHH's 2006 keynote
2) Episodes 35 and 67 of Railscasts

If anyone can add to this list, please drop a comment!
