An absolutely amazing social media marketing campaign by Ben & Jerry's promoting social responsibility and fair trade. This is such an incredible idea! Ben & Jerry's created a Twitter application that allows users to use leftover characters to promote free trade. Watch as their algorithm creates a unique message based on how many characters you have left over from your 140 character Tweet. So not only is Ben & Jerry's creating viral spread but they are helping a great cause. Kinda genius. I love it!
