Cool concept! I like the idea and just signed up. Will definitely give it a spin and give some deeper insight. The design is sparse (almost in a good way). If I were you, I'd think of some ways to tighten up the feel. Rip off some other webapps' design features (header/footer style). I know this is sort of a "feeling it out" run so carry on. :-)
