A Google+ post by Paul Allen, founder of ancestry.com and a self-proclaimed “unofficial Google+ statistician, shows significant growth of Google’s social network since opening to the public. These growth rates were only first seen during the first few weeks of field testing when the user numbers were very low. In terms of the current growth spurt Allen states:

@TatWZA @Yungjohnnybravo

“it is clear that Google+ is absolutely exploding — 30% growth in just 2 days and with a base of nearly 30 million members already.”

His previous Google+ users estimate was 28.7 Million users on September 9th a number that has increased to 43.3 million  current users.  He also stated that “most of the growth coming in the last 2 days.”

So what does this mean? Google+ may be cementing themselves as a credible social network, but the mass exodus from Facebook just isn’t happening. Facebook is still the powerhouse network with 800 million+ users and all of the layout complaints aren’t adding up to astounding departure numbers … yet.

Other notable Google+ timeline stats are:

  • Over 1 million mark (1.7 million) – 7/4
  • 4.5 million user mark – 7/10/11
  • 10 million user mark – 7/12/11
