The finance piece of MOOCs is important and it still looks to me like only StraighterLine is addressing it. I read yet another article on poor pay for adjunct instructors. Will mentor pay be any better? (Assuming MOOCs move us towards a mentor model rather than the traditional faculty on the stage model.)
In the online world it does feel to me like the interaction between learners and instructors and between learners and other learners is necessary to developing critical thinking skills. Both of those forms of interaction require skilled activity on the part of the instructor which translates into time on task. If education becomes more individualized that will possible require more time on task... and more funding.
