"Two things make this kind of innovation possible, one obvious and one not. The obvious one is--say it with me--the Internet. The other one, the surprising one, is a curious phenomenon you could call intellectual altruism. It turns out that given the opportunity, people will donate their time and brainpower to make the world better. There's an online encyclopedia called Wikipedia written entirely by anonymous experts donating their expertise. It has the unevenness you'd expect from anything that's user-created and user-edited, but it's still the most useful reference resource anywhere on- or off-line; earlier this month Wikipedia posted its 1 millionth article. You would think corporations would be falling all over themselves to make money off this new resource: a cheap R&D lab the approximate size of the earth's online population. In fact, they have been slow to embrace it. Admittedly, it's counterintuitive: until now the value of a piece of intellectual property has been defined by how few people possess it. In the future the value will be defined by how many people possess it."
