Kevin Kelly has it right. "To raise your sales out of the flatline of the long tail you need to connect with your True Fans directly. Another way to state this is, you need to convert a thousand Lesser Fans into a thousand True Fans. "
It seems that, for many, the sale is the end. That just can't work anymore. It has to be the beginning of a great relationship. A "true" fan is one who keeps buying, but more importantly, talks you up among their friends.
