Google's social network, Google+ is one of the fastest-growing nets ever -- if Paul Allen's calculations are correct. Allen, of Ancestry.com, has an interesting methodology for calculating the number
of Google+ members. He sampled surnames from the U.S. Census Bureau data and compared it to surnames of Google+ users. By comparing surname popularity in the U.S. with the number of users on Google+
with each surname, he guessed the percentage of the U.S. population that signed up for Google+.
Then Allen calculated a ratio of U.S. to non-U.S. users to generate an estimate for
the number of Google+ users worldwide. The result? Google+ has approximately 9.5 million users worldwide, with 2.2 million joining in the past 32 to 34 hours, according to Allen's calculations. If the
numbers are real -- and Google has yet to comment -- they may suggest another area conquered by the search giant.
10M is what percentage of Facebook's base? About 1.3%. And this was achieved at what cost?
Bing has single digit market share in search, does anyone believe it will take over Google in that market?
Capturing early users who are curious is one thing, keeping them -- and adding to them in orders of magnitude -- is something entirely different. How long will it take (if ever) and what will it cost? Forbes.com says "Google Plus is a Big Minus for Investors" for this reason http://onforb.es/iPp4sG
