Nice layout, easy to read, fast loading. Great job.
The only improvement I would recommend is to make the center column fluid soyour site displays better on smaller screens and can expand to fill larger ones. I had to expand my browser to fill up almost my entire 17" screen before the horizontal scroll disappeared. I've noticed this problem on many Geeklog themes including some of the default ones. People are designing sites for large screens when in fact 50% of the online population are still using 800x600 screens. A fluid design takes care of both groups.
