But his blog entry published this past weekend was great:

Prediction markets are interesting tools, but the lessons learned from public prediction markets are different than those learned from internal prediction markets. It’s important that these two applications are not confused. There will always (and rightly) be questions about the accuracy of prediction markets. In some cases it’s clear that markets are superior, in some internal cases it doesn’t matter since nothing is forecasted right now, and in other cases markets will be about as accurate as what’s already predicted. But in all three cases there is still a valuable argument as to why prediction markets should be used.
