This is the second good crowdsourcing idea I've seen in just as many days. Ripley, a Chilean clothing and footwear company, wanted their catalogue to be a little different than all the other catalogues. They set up a outdoor photo studio, and invited all their fans to come and be the photographers which meant photos shared on every social media imaginable. The final results were then uploaded by Ripley, and the photos with the most votes got to be printed in their catalogue, together with the photographer's name. Pretty good idea.
