I think coursera is amazing, i've finished a few courses signed up for a lot more. It's great, some i stopped because I wasn't really interested in, others I stopped because I got what I needed. I think it's truly amazing and I think completion is the wrong metric; maybe hours of instruction divided by average per course would be better.
