We are working on using data from social networks to classify interns into red, blue and yellow based on reputation to help recruiters source better. As a recruiter/startup CEO, does that sound valuable?

We want to build the learning graph(http://jonbischke.com/2011/02/11/learning-graph-reputation-graph-massive-disruption-in-higher-ed/)and have been looking for an entry point and the intern-recruiting space looked like a great entry point. What would be some other ideas using big data in education?
