Facebook took over 3 years to achieve what Google+ has done in just 3 weeks - hit the 20 million users milestone.

The figure has been estimated by web analyst ComScore, a number that is double the 10 million figure stated by Google CEO Larry Page just a week ago.

Sure, Google+ is still 730 million users shy of Facebook's 750 million figure and sure, we're living in a much more social network powered world now than when Zuck and co launched The Facebook from their Harvard dorm room in February 2004 - but the growth for a platform still officially in a limited field trial stage is phenomenal nonetheless.

It's certainly impressed ComScore's vice president of industry analysis Andrew Lipsman. "I've never seen anything grow this quickly," he said. "The only other site that has accumulated as many new visitors in a short period of time is Twitter in 2009 but that happened over several months."

ComScore has also ranked the amount of Google+ers by country and the UK sits in third place with 870,000 users, behind India with 2.85 million +ers and the US with 5.31 million.
