Big head Quote by Herb Sorensen
““Shoppers are attracted to the store by the long tail, but when they get there, they buy the big head (the vital few). The 50 million books Amazon carries encourages me to think they will probably have the few a month that I want. But they would be out of business (I think) if each time I came through their virtual door, they started from scratch to identify what I most likely want to buy.””
