A way for CEOs to put their finger on the pulse of their company?

A while back, Dubner blogged about this website, which tracks moods of the populace. It has some updated information on how Hurricane Katrina made people feel.

Wouldn’t it make sense for companies to build something like this into their internal networks? It would allow top managers to have up-to-the-minute information on the state of the employees’ mindset. Done anonymously, people could be honest. Not like the happy faces that they put on when they know the bosses are going to be making a live visit.
