Google+ Dec surge
By Asha

Paul Allen founded the hugely successful Ancestry.com and now describes himself as an unofficial Google+ statistician.  Paul has crunched the numbers to chart Google’s meteoric growth in Dec, 2011 and come up with the following

“
Here is what the tracking shows so far:

July 13 - 10 million
August 1 - 20.5 million
September 1 - 24.7 million
October 1 - 38 million (Larry Page announced "more than 40m users" on Oct 13th)
November 1 - 43 million
December 1 - 50 million
December 27 - 62 million
January 1 - 65.8 million (forecast)
February 1 - 85.2 million (forecast)

What is really remarkable is that nearly 1/4th of all Google+ users (24.01% to be precise) will have joined in December alone.

Paul is predicting that Google+ would have 400 million members within 1 year.
