I've added links to collected writings by Malcolm Gladwell and Sherman Alexie. They're under the "Websites I like" sidebar on the left-hand side of the page. I strongly encourage everyone to check out both of them -- these guys are so good!
You might know M. Gladwell from a business school class; he's the author of The Tipping Point and Blink, which are excellent books about consumer/market behavior. He does a really great job of researching his material, and then a really great job of writing in an entertaining and informative way. If I could switch lives with anyone for a day, it might be M.G. (I'd also dig having that hair...)
You might know S. Alexie as the winner of the 2007 National Book Award, or maybe as the screenwriter of "Smoke Signals," a very funny/slightly sad movie. Mr. Alexie writes fiction and nonfiction about his life as a Spokane Indian living in the United States -- so again, consumer/market interactions, from a first-person perspective. In social research, this is known as autoethnography; S.A. is very good at it.
