Google Chief Executive Officer Larry Page has confirmed that Google+, which remains in its trial stages, has more than 10 million users.

However, the growth on Google+ has been great--and I'm excited to release some new metrics for you today, Page wrote on his page. Over 10M people have joined Google+ Great achievement for the team.

There isn't any doubt that Google+'s popularity among users is growing.

Based on his analysis, founder Paul Allen has estimated if the Google+ invite button remains active, some 20 million people could use Google+ by this weekend.

But it isn't just the users that are growing on Google+. Page said more than a billion items are being shared and received each day.

We have substantially increased our velocity and execution this quarter--a key goal of mine since taking over as CEO, Page wrote. It's why I created a new, product focused management structure--with a clear leader responsible for each product area. This new management team is working together fabulously ... and has already achieved a lot in just three months.

Page said the company's goal with Google+ is to make sharing on the Web like sharing in real life, and to improve the overall Google experience.

Users can create Google Circles where they can precisely decide who they are sharing with.

Not surprisingly this has been very well received, because in real life, we share different things with different people, Page wrote. Hangouts allow for serendipitous interactions. Like in real life when you run into a few friends.

Google launched the Google+1 button last quarter in search results and ads so that user may recommend things they liked and have their recommendations show up in the search results of the people they know. The +1 button was released to the web this quarter.

Our +1 button is already all over the Web, Page wrote. It's being served 2.3 billion times a day. So while we have a lot of work still to do, we are really excited about our progress with Google+.
