Excellent project! I'm going to play with it, and possibly list it as a resource in our Data Analysis Learning Path at SlideRule. Excited to see how it evolves.
I love the idea of this. We are constantly educating people about data basics when they are building viz and interactive sites with @silkdotco (I work there). Once people get basic data concepts then they become pretty quickly capable of building a better schema and structure. And data munging should be a 101 skill in any B-School, I think.
