Pepsi Refresh Ideas Competition

Pepsi is organizing its corporate philanthropy around investments in new ideas.  Pepsi's interest in new ideas gets at some of the fundamental principles of social entrepreneurship: finding pattern breaking solutions to solve enduring social problems.  The competition is called Pepsi Refresh and it allows you to nominate, review and vote on the organizations Pepsi should support, based on the ideas you find most compelling.  Check out the site.  What do you think of the ideas on the site and/or this approach to developing new ideas to create social value?
