"Whether or not somebody from Vancouver who has a love of learning can someday receive course credits from Harvard without leaving their living room remains to be seenm" says an editorial in The Columbian. "But for now, the idea of taking "Introduction to Astronomy" from Duke University, plus "Developing Innovative Ideas for New Companies" from the University of Maryland, plus "A History of the World Since 1300" from Princeton University is a delicious prospect." This is the bottom line. Everything else is about models or marketing or some such detail. The main thing is the opportunity to learn for free online. That one detail trumps everything else.
