I think it is important for us as teachers to offer a huge spread of courses from Plato, the deadest white male around, to very modern philosophy.

That's just a huge spread. We think if you allow people to participate directly, it's a more efficient marketplace. People can make a better return on their deposits, which then become the source of credit to others.

Masters, spread yourselves.

The one thing you've got to say about Columbia is that it has courses that are famous. It has alumni who come back and say it was the best thing they ever did.

No bubble is so iridescent or floats longer than that blown by the successful teacher.

I just think it's unfair what they are doing given the big, huge raises they got.
