"Open Culture: The best free cultural & educational media on the web"
Links to literally hundreds of free online courses, free movies, free e-books, free audio books.free textbooks and other free educational stuff. A good place to start: "A Master List of 1,000 Free Courses From Top Universities: 30,000 Hours of Audio/Video Lectures".
It's a good thing they didn't have all this available when I was a teenager. I never would have graduated high school, let alone college.
