One of the clearer explanations of the value of MOOCs and the lessons to learn from a few of those that have been playing the game for a couple of years. The big take-aways (well -  I'm highlighting the things that I have said before and therefore agree with) are to build small and build diverse. Nothing new here: the idea of the JOLT alluded to in the article can be traced back at least as far as the (just) pre-web JITOL project in the early 90s, the suggestion that Stanford invented the MOOC is laughable, and some of those quoted do not want to lift their heads entirely out of the sand, but there are some useful hints here of where things are going and why this is a disruptive change, not just a free variant of something old.
