I've just completed my Rails Rumble contest entry for this year. I took a very focused project, and built it as a single solo developer. I'm extremely pleased with the way it turned out.

The site was inspired by a recent post over at kottke.org about "The Steve Ward" diet (see Kottke's source article from Philip Greenspun, it's a good read... and not actually about dieting).

After reading about this simple diet strategy (it's nothing more than a graph paper of your daily weight), I decided to try it for myself; it works. I've lost 8 pounds in about 3 weeks. My success is mostly due to more frequent and longer trips to the gym--the motivation for that has come directly from the accurate daily feedback you get from this plan.

The web site is a slightly more sophisticated version of the paper-and-pen version Steve Ward describes.
