CRB wrote a very inspiring review of the Long Tail in her blog:

Chris Anderson, in his interesting book, The Long Tail, says: “When the tools of production are available to everyone, everyone becomes a producer.” He’s talking in the context of the explosion in computer technology and internet access to software that allows ordinary people to create videos, music, books, and blogs on every conceivable topic, but the thought is an important one in other contexts as well.

If nanofactory is available for everyone, will everyone becomes a producer? Could be, but that may not necessarily means that there will be no majority producer who controlled the market. There will still be trends and hits, but would it mean that the tail becomes longer?
