The MOOCs may have some business challenges with a 90% failure rate, assuming they intend to make money from graduates, but it is no indication of problems with the service from an end-user perspective. I've signed up for a few courses now with no intent of using them as a school, just as supplemental material to augment my own personal learning venture. I don't really care about the tests or homework prescribed by the service, and I certainly don't care about any kind of certificate of completion. I don't consider my usage habits a failure though. In each case I came away with what I had hoped to learn when signing up.
