I just have to say, this is incredible if you work in WordPress and use coda: http://pradador.com/code/coda/wordpressmode/
also, here are some WordPress clips for coda: http://coda-clips.com/category/wordpress
Also, completely unrelated: this site is a great representation of responsive web design: http://hicksdesign.co.uk/
and I just love the colors and the awesome use of jQuery in this one: http://www.seattlesbest.com/
What are some sites you've been loving recently?
