Thanks for walking with me through some of Malcolm Gladwell's work. I invite you to visit his site at www.gladwell.com where there are monthly articles on a variety of subjects. Also, there is a great descriptive interview that sums up concepts in Blink that I'd recommend, too.
To me a lot of life and theology is kind of like an iPod... it's very complex and fancy, but without a cheap pair of headphones there is no application. People like Gladwell serve as those headphones for "the rest of us."
