Ruby / Rails Blogroll (What's on yours?)

I'm not a ruby/rails guru, but I've just started a blog using Mephisto at
http://www.flyingmachinestudios.com/blog . My first two articles are on
thinking about mental models in regard to user experience - not strictly
rails, but I plan on writing an article on creating a macro for Mephisto.

There's also Rick Olson's blog, http://weblog.techno-weenie.net/
