This site is built in Drupal 7 using the following modules:
And a little bit of glue code here and there. No, not even Views (for now.)
The theme was created from scratch by me using Zen as a base theme. I mainly chose Zen because I know John and can guilt him into helping me when I need to. It is called heyrocker and I've put it up on github. Note it is not particularly full featured. It is my first theme and only covers what I needed on this site, and a lot of the techniques are probably really awful. The color scheme of the theme was inspired by my Textmate theme, which is a modified version of Tomorrow Night - Blue by Chris Kempson. You can also get this on github. The fonts are Inconsolata (also my editor font), Gil Sans and Droid Serif. Its not the best theme in the world but I'm pretty happy it came out not too ugly.
The social networking icons came from Alex Peattie. They are really great.
