EricRaymond has a response to the question of GettingPaidForContent.
Some goods are identity goods, that you buy to establish your identity. These include books, music etc. So content which is also an identity good will sell.
Maybe it's true you can't put a web-site on your book shelf. But I can put it in my BlogRoll. Maybe if I take me online life seriously, physical manifestations of identity goods will lose their value.
