See this article which describes what a long tail is, and this pdf with the less-than-inviting title of “Consumer Surplus in the Digital Economy” by the MIT eBusiness research center which says that 57% of all Amazon sales come from long-tail books.Warning: this pdf uses functions which you’ve never encountered in your college math class, and introduces you to characters you will never meet again outside of a shady bar in Cambridge, Massachusetts. So just take it from me, the long-tail is a great place to be. Culture always thrives on the fringes, and withers under the spotlight.
