I second what Po Bronson says about "Buying In." This book is much more than a simple, cocktail party business book -- it's an attentive, subtle and entertaining meditation that not only uncovers the latest trends in buying, selling and marketing but also pushes us to consider larger questions beyond these subjects. Personally, since finishing the book, I've taken a harder look at my purchases and what they mean to my larger sense of identity. Not that this is some kind of Chicken Soup for the Marketing Soul, but Walker isn't afraid to follow his many case studies and pieces of hard evidence to wherever they lead, and sometimes that means not only a critique of consumer culture but a look at contemporary American culture as a whole. And that's what I love most about this book -- that Walker dives into consumer culture with such wide, bemused eyes. The reporting reminds me of Studs Terkel -- when a journalist can turn a subject into something wonderful, literally into something "full of wonder." I was happy to follow marketing detective Walker on his tour of energy drink kitesurfing, dive bars, chicken sausage cookouts, underground dance parties, and Lower East Side sneaker boutiques. (As someone who almost got kicked out of an "underground" New York sneaker boutique for merely trying to, um, shop, I was pleased to have Walker pull my coat on this corner of underground brand culture.) And where his tour leaves us, at the end of the gripping final chapter, is in a place that is somewhat contradictory and unexpected and completely fascinating.
