Google+ is now open for teens

In move that we’ve anticipated for a while, Google+ is now open to everyone 13 and over, rather than the 18 and over policy they’ve had until this point.  Specifically, Google+ is now available to anyone that is old enough to have a Google Account, which is 13+ in most countries.

Personally, I like the move.  While teens will likely bring a lot of content that I’m not interested in, that’s not a problem thanks to the circling model; I just won’t circle anyone who posts content that I don’t care to see.  In the long run this should help the growth of the service, which is good for all of us.

Google+ reaches 90 million users

Google+ now has 90 million users, according to a statement that Google released today:

Google had a really strong quarter ending a great year. Full year revenue was up 29%, and our quarterly revenue blew past the $10 billion mark for the first time,” said Larry Page, CEO of Google. “I am super excited about the growth of Android, Gmail, and Google+, which now has 90 million users globally – well over double what I announced just three months ago. By building a meaningful relationship with our users through Google+ we will create amazing experiences across our services. I’m very excited about what we can do in 2012 – there are tremendous opportunities to help users and grow our business.

Congrats to the Google+ team!

Google+ has over 10 million users already?

Last week, we showed you Paul Allen’s work on trying to determine how many users were on Google+.  At the time, he was estimating around 1.7 million users.  Now he is estimating there are over 10 million users on the site, and that number could grow to 20 million by the weekend if the Google+ invites remain open.  Wow!

As before, the math is certainly inexact but has some sound logic behind it.

My model is simple. I start with US Census Bureau data about surname popularity in the U.S., and compare it to the number of Google+ users with each surname. I split the U.S. users from the non-U.S. users. By using a sample of 100-200 surnames, I am able to accurately estimate the total percentage of the U.S. population that has signed up for Google+. Then I use that number and a calculated ratio of U.S. to non-U.S. users to generate my worldwide estimates. My ratio is 1 US user for every 2.12 non-U.S. users. That ratio was calculated on July 4th through a laborious effort, and I haven’t updated it since. That is definitely a weakness in my model that I hope to address soon. The ratio will likely change over time.

You can read his full write-up here.  Do you agree with his logic?  Can we really already be at 10 million users?

How many users will Google+ Get?

A few days ago, Paul Allen estimated that there are 1.7 million users on Google+, based on distribution data from the US Census Bureau.  It was quite a creative solution, and should be reasonably accurate. Specifically:

Today I squeezed in enough time before and after our local parade, and before our Fourth of July picnic to update my model and do a much better analysis. I increased the sample size from 50 surnames to 79 (I would have done 100 but ran out of time), and I split out users from the US and from outside the US. I had to look at hundreds of profiles to determine US vs. non-US. Unfortunately, not everyone lists their location yet, so I had to infer it sometimes from their circles and language they were using. Sometimes I found them on other social networks and could resolve the question that way.

Google+ currently has 515,933 users in the U.S, and 1,226,136 outside the US for a total of 1,742,069 users.

Now he wants to take it further and try to estimate how many users may ultimately end up on the service.  To do that, he’s put together a very short 5-question survey, and he promises to share the results of it when complete.

When we hear the results of it, we’ll be sure to let you know.
