There will continue to be low retention until there is an incentive to finish. Without the credentialing piece, I don't see a problem with low retention. I think it's awesome that people dip in and out as their needs and interests change. In every class I ever took at MIT/Caltech there were at least a couple lectures I would have been happy to skip. MOOCs enable that. I hope there will be more short and tightly focused online courses in the future instead of monolithic traditional-length courses we have today. I think that'd go a long way to improving the apparent retention rate.
