Udacity has done what any good start-up should and launched a solid MVP and iterated on it, delivering free, in-demand courses in a short amount of time. No, the materials and scripts have not always perfect but they are still more valuable than many college courses I've taken. If he is in fact leaving to focus energy on Udacity, isn't that a positive move in regards to your critiques?

Yes, you make a good point. My opinion - and that's all that it is - is that his (many) abilities lie in the Google [x] direction, not as a poster boy for MOOCs.

I've recorded my self and many others teaching: there is only terrible teachers, and people who survive the humiliation of seeing themselves try more than twenty times. I would never let anyone watch any of their first five takes first.

But who are we to say where he should apply his abilities? He may be interested in something new and that is where his next best contributions lie.
