 The hoodie-wearing CEO has over one billion "friends" but he's expanding his influence with lobbying group FWD.us, which advocates for immigration reform and technology education. Zuckerberg donated 18 million Facebook shares, worth $500 million at the time, to the Silicon Valley Community Foundation in December 2012 for education initiatives.
