There needs to be a point?
Great list but just scratching the surface. I wonder why Kahn is not mentioned or linked. Most of the courses with particular curricula at Stanford, MIT and manu other colleges and universities are available free, online--some issue certificates of completion. Some of the Stanford courses have fees, but most don't. Great way to spend your TV time. http://online.stanford.edu/courses/allcourses
The MIT OCW classes are awesome. I started a few but dropped them when I got busy. I need to pick them back up again:https://ocw.mit.edu/index.htm
If you need a point, it's simply that the best education in the world is available for free to anyone who wants to access it, from anywhere. This is unprecedented in human history--but then again, what isn't.
