There has been a lot of chatter about the "long tail" in the web industry as a new business model. Now there is a site to help you build a long tail! It's called MyLongTail (blog).
They have some very interesting graphics to explain what they do (explaining concepts like this is not easy to do)
Their business cycle graphic "works" quite well to explain how things can work.

This has been one of the very first blogs to recognize and blog on our new service. It’s the end of June now, and the soft launch beta has only been out for about 4 weeks. Mark ID’d it as significant in like the first day. Anyway, we’ve renamed our service to HitTail (as in HitTailer, HitTailing, etc.). And we’ve developed a nifty new demo to bring the ideas down a few notches. http://www.hittail.com/demo/ Thanks!
