Washington Post profiles Facebook cofounder and his wife, whose philanthropy focuses on "anything that could seriously derail humanity’s progress".
"Tuna and Moskovitz were in their mid-20s in 2010 when they became the youngest couple ever to sign on to the Giving Pledge, the campaign started by Bill Gates and Warren E. Buffett to encourage the world’s billionaires to commit to giving away most of their wealth. They had little experience with philanthropy, but they believed that the bulk of the money Moskovitz had made — estimated to be $8.1 billion by Forbes — should be returned to society in their lifetimes. The question was how." -- Ariana Eunjung Cha, the Washington Post
