Oh and to answer my own question I've most recently made my way through 3/4 of
Freakonomics, by Steven D Levitt and Stephen J Dubner. Interesting book - kind of reminds me of
Malcome Gladwell's
The Tipping Point and
Blink.
And just in writing this post I've discovered Freakonomics has a
blog, too, though at first glance the content doesn't seem much like the book.
