They're too long. Once in a while I enjoy spending 5 to 8 hours on a Saturday learning about something new, but MOOCs often ask for an entire semesters worth of my time. I don't have that much time, I have an occasional Saturday. Divide the courses up into free-standing bite sized chunks, something I can go through in a day, and let me complete them on my own time. I'd complete more of them if that happened. That should also force brevity, which was lacking in a lot of courses I tried.
