Although I haven't yet read Freakonomics, I'm riveted to the tv every time the author, Steven D. Levitt, makes an appearance. His research has bought to light some information and theories that just aren't available elsewhere; the economics of drug dealing gangs, for example.
What a thrill it was to learn that he and co-author Stephen J. Dubner have a Freakonomics blog.
It's a fun site in which to browse around. And it's not all economics. The little bits of gossip, such as speculation that Al Franken has taken up residence in Minnesota in anticipation of a run for senate, make for juicy reading.
