Oh yeah, I almost forgot to mention this. I've teamed up with with Forrest Chang to focus on polishing Emacs' Rails support. I've written up a tutorial (still in progress), and there's a discussion page on my wiki where you can have your say. Forrest is planning on putting up some nifty screencasts, so stay tuned.
Also, Planet Caboose is all official now.
Lastly, this web comic is pretty funny.
