One thing that is interesting to me about the long tails reading is that there is incredible amounts of efficiency built in. The reason why the market would cut off the tails and just go for everything within a standard deviation on a bell curve is because of the amount of productivity it would have to spend in order to gain those niche markets found near the ends of the tails. In the new markets that productivity is still spent, however not by the publisher. By allowing for peer to peer input, and a digitally distributed business model, we have productivity spent by the user (in a PTP setting).
