Changing the Definition of "free"

I don't remember much of my economics education but I did walk away with the idea that it usually wasn't a good idea of your supply outpaced your demand and vice versa. Chris Anderson, editor-in-chief of Wired, recently wrote an article about the economics of "free" and how the combination of technology and "free" goods contradict some of the traditional economic models. You can find the article here (thanks Seth Godin).
