Show HN : Class Central - Summary of Stanford's free online courses

Built most of it over the Thanksgiving weekend and here is the result:

www.class-central.com

Built in PHP/MySql using Symfony2, Doctrine and Twitter Bootstrap. Source code can be found here:

The 'extras' folder in the repository contains a dump of the database dump(with all the data you see on the site) and the schema.

I have also created a circle of all the instructors with Google+ accounts:

Any feedback/suggestions would be appreciated.
