If you are on Twitter you might know this already, but I just released my first public WordPress theme, Professor (those who saw it a day-or-so ago saw a buggy version with tag-cloud wonkiness, but that's been fixed). It's a single-column theme that doesn't require any plug-ins, and best of all, it's brown (I like brown)! It's simple and straight-forward, and I think I'm pretty happy with the result. Anyways, the theme page is here:http://protocol7.net/themes/professor
Additional info: it has a 'featured posts' display, is valid XHTML 1.0 Strict and CSS 2.1, and released under the Creative Commons Attribution-Share Alike license (the GPL *confuses me*).
