Google+ only launched last week, and it looks like Google+ may be about to hit its first milestone of 10 million users, according to Paul Allen, the founder of Ancestry.com who has been monitoring Google+ growth.
According to Paul’s numbers, Google+ reached 7.3 unique users on the 10th of July, and it is expected to reach the 10 million mark by some time today, the 12th of July.
I project that Google will easily pass 10 million users tomorrow and could reach 20 million user by this coming weekend if they keep the Invite Button available. As one G+ user put it, it is easy to underestimate the power of exponential growth.
According to Paul’s estimate, Google+ could reach 20 million users by the weekend, which certainly seems impressive, considering the service was only launched recently.
