We live in amazing times. For the majority of those of us who live in America, we have vast reservoirs of free time. But how do we choose to use that free time? Sadly, for the last fifty years, we have spent most of it passively watching television, watching television to the exclusion of other more social, more fulfilling activities. Last year, in fact, Americans watched about two hundred billion hours of television. And, even more sadly, studies show that those who watch tv are less happy, more overweight, and less social. Shirky begins his book with this information, but he does have happier news to report: Americans are gradually beginning to turn off the tv in favor of other, more interactive activities. Shirky looks with great hope at the new social media that allows users to accomplish big social projects in easy ways. A book that is definitely worth reading.
