The site is interesting. I like the meal swap approach -- normally I get cravings for a particular meal so I can just put that there and get a healthy substitute -- nifty.

Some things I've noticed so far:

* in signup, it would be nice to be able to specify meters vs feet. I had to google the conversion

* in signup, 'inactive' looks clicked, had to think for a sec before noticing it wasn't (and the signup form wouldn't let me sign up)
