Google+ has been growing at an alarming rate, that much is clear. And thanks to the unconventional, but sometimes accurate measuring system of Paul Allen (Ancestry.com), Google+ seems to be raising its numbers at a staggering pace.

Using his ‘uncommon surname’ system of measuring user numbers of the new social network, Mr Allen is reporting that Google+ now has over 43 million active users. Mr Allen reported that on September 9, Google+ had an estimated 28.7 million active users. That number jumped to 43.4 million active users on September 22^nd. So what happened there? It seems the fact that Google has lifted the social network out of beta and made it publicly available has triggered a ‘feeding frenzy’ of sorts. According to Mr Allen, in the 2 days since users were able to join without an invite, Google+ grew by an estimated 30%.

The question is whether this level of growth can be sustained. If it can (and many doubt that), Facebook will have its hands full in a matter of months. If it can’t, Google will end up throwing perhaps billions down the drain in pursuit of its ultimate Facebook Killer. Odds are that growth will slow, but Google+ will still climb and be a threat. In fact, many are speculating that many users of Facebook will gladly join Google+, if only for the opportunity to have and use a second option. It may be 43 million today, but if Mr Allen’s maths is correct, it could very well be 150 million by the end of the year.
