Sweet. I'm one of the developers :)

Regrettably, the site is moving really slowly. We made this for the Rails Rumble earlier this year, in 48 hours. After that, very little time was devoted to the site, since our "real" jobs keep getting us from hacking on this.

If you have any ideas, however, I would encourage you to go and add them to our support system, at http://help.howsmycode.com -- we don't promise to get them implemented right away, but we will look at them :)
