i think it's a pretty cool idea...no reason why university level education should cost $30k a year and be limited to a small group with all the internet technology available now...there are a couple major issues that the article mentions like cheating and grading...another one i would think would be a problem is credibility...online education is still considered inferior to in-class instruction...the lectures are the same since they're recorded, but students in a real university setting interact and learn from professors, TA's, and other students...online students would miss out on a lot of that...still a very good idea to make education more accessible
