I'm becoming a great fan of watching/listening to TED Talk podcasts. I just watched one I wanted to pass along...
It's about the Game Layer to the world, how it's being played already, and how we might leverage it in the future in ways that benefit our lives. The guy giving the talk, Seth Priebatsch, gives some real-world examples of all of the above - and I found it very fascinating once I got used to his kinda odd accent. It's not too long, is very enlightening, and really makes one think.
Just wanted to share.
