I quite enjoyed reading Freakonomics by Steven Levitt and Stephen Dubner. Though I had mixed feelings about it as a book by itself, I think it raises several clever points. That tradition is continued by the two authors on their blog. I frequent it often and most of the time it is worth my while. After more than two years of independent existence, that blog now lives in the exalted locales of the New York Times. I suppose they will attract more audience now and pocket a bigger sum.
