Zuckerberg: In 10 years, folks will share 1,000 times what they do now

"It's sort of a social-networking version of Moore's Law," said Zuckerberg, who was interviewed by Y Combinator co-founder Paul Graham. "We expect this rate [of sharing] will double every 10 years. So in 10 years from now, people will be sharing about 1,000 times as many things as they do today."

As for Facebook, he argued that the social network is fundamentally changing human behavior by expanding the number of people we can keep in our social circles -- offline and on.
