A Love of Learning

I read a lot about education and learning, and let me just say the idea of Khan Academy is awesome.  Literally.  I love the idea of essentially offering free classes and tutoring to anyone (with the limitation that they need internet access).

Other good sites for learning online include http://academicearth.org , http://www.openculture.com, and http://oedb.org/library/beginning-online-learning/200-free-online-classes-to-learn-anything 

And they aren’t just for kids!  Share other sites you’ve used to learn specific skills or knowledge content.
