The big problem with projects like this is the quality is pretty much lacking. Most of those MOOCs to begin with are no way intended to replace the equivalent college class. Most of them are watered down introductions to the courses. At a baseline for me to take any MOOC seriously then I want to see a high-quality textbook (or equivalent) for the course. If that doesn't exist then my opinion is the course is likely to be of low-quality. I'm sorry but replacing a textbook with a series of online blog articles or tutorials is simply not a sufficient replacement.
