Great post today by Chris Anderson, author of the Long Tail about “spare cycles.”

The basic idea – people have always had excess free time. The technology behind Web 2.0 now gives them the tools to do something useful with it…like build an encyclopedia.

From the article:

In physics, the greatest (theoretical) latent power in the universe is dark energy, waiting only for us to find a way to tap it (and to prove it actually exists; in the meantime it powers fictional superheroes). In people, the equivalent is “spare cycles”–the human potential that isn’t tapped by our jobs, which for most of us is a lot of it. People wonder how Wikipedia magically arose from nothing, and how 50 million bloggers suddenly appeared, almost all of them writing for free. Who knew there was so much untapped energy all around us, just waiting for a catalyst to become productive? But of course there was. People are bored, and they’d rather not be. The guy playing Solitaire on his laptop at the airport? Spare cycles. Multiply it times a million.
