This is interesting, but I think completion rates (and enrollments, to a degree) are bogus statistics. All the incentives are aligned toward signing up for lots of courses, with or without any intention to finish. I'm "enrolled" in 13 Coursera classes at the moment, but only active in two (and something close to this has been my moving average for the last six months).

The only cost to me is a few too many automated emails. And since course quality still varies widely, trying out lots of courses and sticking with the best ones is a good strategy.

Yeah, I've signed up for about a dozen Coursera, Udacity and CalTech courses over the past year, and finished 3 with enough work for certificate of completion, and put in enough work on a few more to get something out of them.
