David H. Freedman is the latest addition to our roster of Cool Friends. He's a contributing editor and technology columnist at Inc. magazine, and he's also written for Newsweek, the New York Times, Atlantic Monthly, and Wired, among others. He got together with Eric Abrahamson, a professor of management at Columbia Business School, to write A Perfect Mess: The Hidden Benefits of Disorder—How Crammed Closets, Cluttered Offices, and On-the-Fly Planning Make the World a Better Place. His interview may come as welcome news, depending on what your office looks like. You can read his Cool Friends interview here, and, if you want to learn more, he has a website, too.
