Great site. Very self explanatory. I like that it removes all the hassles of creating, saving, and distributing spread sheets. Definately bookmarking this one.
I agree. The terms are way too restrictive for much use in a mashup. I wish they would revise them because I would love to develop some cool services using the Yelp API. I understand the need to protect ones IP but as an API thier current terms are not very conducive to development and developers needs.
