This is one of the coolest things I've seen in a long time and a great execution of an offline/online idea.To promote his new show on TBS, Conan is sending a blimp up and down the East Coast for the month of October. You can follow it on Twitter or Foursquare for check-ins above his favorite spots. The project also implements the first ever auto-updating check-in location. So, spot the blimp and get a "Conan Blimpspotter" badge. Pretty cool. The talented folks over at Breakfast put this together.
