Check out this great Nike promotion that was run through Twitter and Facebook Places, a perfect example of how real world promotions can be run through social media. Followers of Nike on Twitter were told of a special codeword to use at the Koi Fusion Burrito Truck at a College Football game in the US. They were then required to check-in there on Facebook Places and order the ‘Destroyer Burrito’ which, much to their astonishment, was not a burrito at all, but a Nike sportswear jacket dressed up as a burrito. Brilliant!
