The main thing I got out of this book was to take note of the difference between a'market' and what an artist thinks a market could be. While the writing is fairly competent, it can not be taken as completely self-serving. It seems to suggest that if you give them enough money they'll keep coming, but they won't. There are some interesting ideas there, but they're scattered amongst the clunky writing.

Ex Output:
Bad review

I just received my Kindle 2 in April and after reading the first several chapters found a number of inaccuracies -- from references to British terminology relating to aircraft as something with wings to descriptions showing two British men standing together.
