In 2010, investment leviathan Warren Buffett joined computer mogul Bill Gates and his wife, Melinda, in launching the Giving Pledge to convince similarly rich people to give 50 percent or more of their fortunes to charity. On Tuesday 11 new multimillionaires and billionaires joined the initiative. New pledges, including Netflix CEO Reed Hastings and the guy behind those little five-hour energy drinks, join illustrious philanthropists like Mark Zuckerburg, Ted Turner and Michael Bloomberg in agreeing that they can probably do without at least half of their fortunes.
