Luis von Ahn: Massive-scale online collaboration | Video on TED.com
have you heard about the reCaptcha project? or Duolingo.com?
hear all about it here! ( from the person who invented Captcha's!)
looking forward to seeing you all soon
happy new year!

This video is amazing! I went from hating deeply Captcha all the way to consider it as an amazing use of a necessary hurdle.
