FACEBOOK says it now has more than one billion users, but worries remain about how the social networking site can make money from members.

"This morning, there are more than one billion people using Facebook actively each month," he said in a statement.
"Helping a billion people connect is amazing, humbling and by far the thing I am most proud of in my life."
