Something I think which is worth adding under "Emacs Squires" is Rick Dillon's "Hack Emacs" series of videos.

Emacs Golf should be in it (derived from VimGolf)

Golfing is trying to create/modify some data in the smallest keys sequence possible. It's fun and uber efficient to acquire knowledge about editors (and also other people workflow/habits)

Some blog article http://irreal.org/blog/?p=293

Google returns a few more links, suit yourself.

Haven't found Emergency Elisp by Steve Yegge there, and it's a good hands-on intro to Emacs lisp.

Good list, every time I look at other configurations or options for Emacs I learn something new :). Does anyone know if there's been any news on Emacs and Guile?

Great list. I use most of the resources listed there, but really, the Emacs wiki usually answers most of my questions.

we need one for vim. I always feel there's something new to learn.
