Facebook has overhauled its internal search engine to allow members to easily search through their friends' profiles.
Speculation ahead of the announcement helped push Facebook stock, which sank
rapidly on its $38 Wall Street debut in May, to its highest level in months.
Today Mr Zuckerberg indicated investors should not expect a Graph Search to
rapidly become a major new source of advertising revenue.
"I think this could potentially be a business over time," he said. "You build
a good business by first building something that people want."
