Hey Chip,
Are you sure Matt is totally against commercial themes and plugins? I wonder if he is changing his tune since Brian Gardner's Revolution2 theme advertisement was placed in the theme directory? See image here: http://justintadlock.com/blog/wp-content/uploads/2008/12/revolution-ad-wordpress.png

Uh oh, I just checked the theme directory and the Rev2 ad is no longer there. Anyone have any update on this?
