At any given moment, 20,000 project requests from public school teachers are on Best's donorschoose.org waiting to be funded by ordinary people. Since the former history teacher launched the nonprofit 11 years ago, donors have given $70 million to 147,000 projects. Many may get a boost from this fall's documentary about the U.S. education crisis, Waiting for Superman; Best raised funds from donors like Yahoo co-founder David Filo, eBay founder Pierre Omidyar, and Twitter's Biz Stone so that every filmgoer would receive a $15 gift code to make a donation on the site.
