The rant on Simpleface just now was also in part a reaction to the cool UI posts I just ran across.
First, Brett Morgan likes a good UI usability rant and includes a few links to Joel Spolsky's great Usability post and book. Then later I ran across Dave's UI links on his Rolling Blogger weblog. Must be something in the air.
Man, I should just WACK Simpleface and leave a URL redirect to Joel's website... that's a great article.
