DI was not prepared to like “Futureshop” by Daniel Nissanoff. Books about e-commerce tend to be like uninspired sex: a convenient shortcut to a nap. But this one is like the jolt of a double espresso. Who knew that secondary markets could be so interesting? In Daniel’s view, eBay is creating an “auction culture” that is transforming the way we shop on- and offline. After all, when a used car is transformed into a “preowned” Lexus, secondhand status has lost all its stigma. Lee Scott, the CEO of Wal-Mart, is quoted as having no concerns about the threat of Target, but eBay keeps him up at night.
