Quoting Clay Shirky (via Boing Boing):
The price of information has not only gone into free fall in the last few years, it is still in free fall now, it will continue to fall long before it hits bottom, and when it does whole categories of currently lucrative businesses will be either transfigured unrecognizably or completely wiped out, and there is nothing anyone can do about it.
What other industries “sell” information by supply and demand? Where else are there going to be opportunities for the innovators to step in?
