A survey report published by Paul Allen, the founder of Ancestry.com, revealed that the Google+ user-base now stands at 18 million and counting. So, after Google co-founder and CEO Larry Page's announcement of 10 million user, more than 8 million new members have joined in Google Plus in less than a week.
Paul Allen, who accurately announced Google+ user base before Google CEO's Jul 14 keynote, said that though Google+ witnessed explosive growth in last few days, latest data reveals that the growth rate has slowed down little bit.
"Last week we saw two days where more than 2 million signed up in a single day. If that rate had continued, Google+ would have reached 20 million users by last Sunday night. But the last four days have averaged only 948,000 new users and yesterday the site added only 763,000. Yesterday's growth of 4.47% was the slowest viral growth since Google opened up invites back on July 6th," Paul Allen said in his Google+ post.
Paul Allen used US Census Bureau data about surname popularity in the US to track the Google+ growth rate. He compared surname popularity to the number of Google+ users with each surname.
According Allen, Google+ bags nearly 763,000 new users per day and if it continue this trend, then it will take nearly four or five months to reach 100 million users.
The billion dollar question is that how many of the Google+ users have came from Facebook. Mark Zuckerberg, Facebook CEO, recently announced that his social networking platform has more than 750 million users. So, if this 18 million users are from Facebook, its user base has came down to 732 million!
