Ok, so I've been tinkerking with Weblogs over the past week trying to decide what I want to run (I really like WP), and I can no longer igore how much I enjoy the layout/theme of the wp.org site itself. During my investigation of all the blogs I could find I believe I've come across most of the freely available themes and layouts out there for WP, but I have not seen anything like this site. I know the background pattern was provided courtesy of Squid Fingers.
Am I unaware of this layout because 1.5 is my first experience with WP? Is this site on something older?
(I tried to search the forums for wp.org and wordpress.org, but didn't find anything on this topic)
