I re-themed this thing today. I picked up the Canvas theme by WooThemes and customized it to fit my needs.
I wanted to go back to a white background with dark text. Easier to read. I also wanted two columns in the sidebar. Not sure why, just something I wanted to try.
Overall, it’s lightweight and everything loads fast. There’s no major graphical overhead on this site layout.
The Canvas theme was really easy to modify to my needs. It’s basically a theme that has a lot of built in customization possibilities, and it’s easy to configure and put together a nice looking site very quickly.
I like it.
