Oh how we love the power of crowdsourcing, especially those that start online and end offline. This particular crowdsourcing project started on Facebook and ended in a pillow fight. No, seriously.
Rob Bliss of Grand Rapids, Michigan invited 100 of his Facebook friends to meet him downtown for a pillow fight. Those friends invited more friends, and apparently more friends invited more friends because the pillow fight that resulted in Rosa Park Circle was epic and over 1,000 people strong.
Great job Rob, way to use the functionality of social networks to organize this real life adventure for your friends and the 900 other people in Grand Rapids, Michigan that shared your vision of fun.
