Review of "Superfreakonomics"

Maybe I've read too many of these kinds of books or maybe this one didn't have as much "edge" as some of the other "social science for laymen" monographs, but for all practical purposes, "Superfreakonomics" went down the hatch without much impact on the system. It's a month after I finished the book, for example, and all that I really recall is that I enjoyed the experience and that the main methodology appeared to be "randomized experiments." There were a few tidbits that stayed with me (like walking drunk being more dangerous per mile than driving drunk), but I'd have to dig it up again to see if there was anything else that I learned that might be worth hanging onto down the road.
