Same thing about the Washington Post article from earlier today. I'm not sure why it wasn't a direct link to the data with a headline of "Feds release huge hospital cost data base".
I don't know if there is a useful service to pull out of the data (other than analyzing it for journalists) since most people don't have much control over where they are hospitalized and if they do have control, they shop by doctor, not price. Insurance coverage means that I have no skin in the game when it comes to price (unless the insurance company puts a hospital on the out of network list).
