I was thinking an interesting startup would be one that matches people taking online courses into study/support groups. Then each person has to put down say a $100 deposit, and the group only gets their deposit back if everyone in the group completes the course.*

As a bonus the money taken from groups that don't complete the course could be distributed to the groups that did so you could actually make money from taking courses.

Anyone interested in working on this??
