A TED talk to think about this weekend.
In this short (7 min) video Juan Enriquez asks the question:
What happens if Facebook, Twitter, Google, Linkedin, cell phone, GPS, Foursquare, Yelp, Travel Advisor, all these things you deal with ever day, turn out to be electronic tattoos? And what if they provide as much information about who and what you are as any tattoo would?
