We reported about the first achievement that google plus reached 10 million users exactly one week ago.

Now we are happy to announce that google plus has achieved another milestone, ie. 20 million users just a week after reaching 10 million users.

It is really impressive and a exponential growth of achieving 20 millions users in just 3 weeks. One more thing we have to note here is that google+ is still in field trial mode and signup’s are only through invitation.

We believe it’s a great achievement and a clear endorsement  by its users.

Google got it (the social) right at this time and people got exactly what they were looking for in a social network.

Still there is no official google plus statistics from google. The above statistics are as reported by ComScore, HitWise and others.
