Steven Levitt discusses pricing.

A great reminder of the power of optimization, although the problem our startup tends to have is that we never get to that point.

We're always too busy adding and refining features to really take time to measure, experiment and optimize those features in the way suggested. It would be great fun, though.

A case for adpinion.

Start listening at 27 minutes in to hear Levitt talk about "the only person in business I have been able to convince about anything" -- a prostitute. Pretty funny.
