There seems to be a fair amount cynicism around the business model (rather, the lack thereof) for these MOOC services. I personally believe that an interesting monetization model lies in examinations. EdX seems to be exploring proctored examinations with Pearson, but if someone can come up with a credible, non-game-able, non-proctored alternative, there's a lot of value to be created/captured.<p>Completing one of these courses along with the accompanying assignments only takes you so far. Grades in a rigorous examination, however, represent a credential, which in turn sets up much needed (by the candidates taking the course) signaling. Eventually, a lot of employers might end up becoming sensitive to this signaling. A crude example of this can be found here: <a href="https://news.ycombinator.com/item?id=3353543" rel="nofollow">https://news.ycombinator.com/item?id=3353543</a><p>If (and when) someone does crack this puzze and if employers in turn, react to this change, I see a lot of universities more than breaking a sweat. This latent potential is what, IMHO, most analysts / investors are really upbeat about.
