Cognitive Surplus

The New York Times has a nice review of Clay Shirky’s book _Cognitive Surplus: Creativity and Generosity in a Connected Age. Here’s an excerpt:

The time we might free up by ditching TV is Shirky’s “cognitive surplus” — an ocean of hours that society could contribute to endeavors far more useful and fun than television. With the help of a researcher at I.B.M., Shirky calculated the total amount of time that people have spent creating one such project, Wikipedia. The collectively edited online encyclopedia is the product of about 100 million hours of human thought, Shirky found. In other words, in the time we spend watching TV, we could create 2,000 Wikipedia-size projects — and that’s just in America, and in just one year.
