"Pick-a-Prof aims to offer a comprehensive set of tools for students making decisions about courses, classes and professors - tools include a class scheduler and a book exchange that integrates listings from online bookstores like Amazon, while also allowing you to reserve books at some campus bookstores. What’s more, you can rate and review your professors. But the core feature is access to each professor’s grade histories." (http://mashable.com/2006/11/30/pick-a-prof-hooks-up-with-facebook/)
