On September 21, Google opened the doors of its social networking project Google+ to the general public over age 18 — Since then the growth rate has skyrocketed to rates we only saw during the first week of its “field test” — back when it had a small number of users to begin with, the growth rates were of course much higher.
In a Sep 23, Google+ post, Paul Allen, founder of ancestry.com and a self-proclaimed “unofficial Google+ statistician states:
“Google+ is absolutely exploding — 30% growth in just 2 days and with a base of nearly 30 million members already.”
Alen also stated that “On September 9, our model showed 28.7 million users, and this morning, our model shows 37.8 million users that has now increased to 43.3 million current users.” Alen said that “most of the growth coming in the last 2 days.”
The timing on Google+ opening up to the public is interesting. Facebook has made a ton of UI changes this week and is holding it’s F8 Developers Conference – in fact it is just staring now. According to a survey this week by Mashable, 72.2% of Facebook users hate the recent UI changes, including the News Feed redesign. Twitter’s stream was filled with complaints yesterday about Facebook under the hashtag #newfacebook.
Alen also refered to other Google+ stats:
- Google+ passes 10 million users on 7/12
- 4.5 million estimate on 7/9 (actually 12:15ish on 7/10)
- 1.7 million estimate on 7/4
Alen also notes that, “according to FindPeopleOnPlus.com, there are substantial numbers of users from countries like Indonesia, China, Vietnam, Japan, Thailand, and many other countries, which my surname counting approach does not include. So I have decided to add a 5% privacy fudge factor and a 10% non-Roman alphabet fudge factor in my Google+ model.”
