 In the MOOCs, there's Coursera, which is a for-profit company based out here in Northern California. Udacity is a for-profit company. And then there's also edX, which is out of the three, the one that I'm most excited about, which is the one that started as MITX. Then they got Harvard on board. Then they got the University of California and the University of Texas system. And they're doing it as a not-for-profit basis, which at the end of the day, I think, is going to make it easier for them to stay focused on the mission, as opposed to the return on investment. The whole space, it does seem like it's happening, catalyzed by the same dynamics that kind of have brought Khan Academy out there. And I know all of the founders of all of these organizations are all great people. I think at least in spirit, Khan Academy and all of them are attempting to do the same thing in spirit, which is make knowledge that used to be behind paid walls make that free and distribute it to the world for free.
