Clay Shirky: How cognitive surplus will change the world

While we're waiting for Kim to arrive back from her epic journey to Europe, her globe trotting sparked some of us to consider how our ability to use near-real-time tools like blogs, Facebook, Twitter, etc might change the world. Although that sounds like a lofty goal, it's happening sooner than we think.

So, in that spirit, and since its Friday, I invite you to take a few minutes to watch Clay Shirky, via the influential TED talks series, talk about "'cognitive surplus' -- the shared, online work we do with our spare brain cycles. While we're busy editing Wikipedia, posting to Ushahidi (and yes, making LOLcats), we're building a better, more cooperative world."
