Google+ may surpass 10 million users just two weeks after its launch. The numbers don't come from Google, but from Paul Allen, the Ancestry.com founder who posted on Google+ the results of a "surname-based analysis" which "shows that the number of Google+ users worldwide reached 7.3 million yesterday (July 10) — up from 1.7 million users on July 4th. That is a 350 percent increase in six days."
