Google+ reached to 20M Users,It will hit 100M users inside of three months

Google+ lets people share comments, articles, photos and videos with various "circles" of friends or contacts, or they can share content publicly with any userwho wants to view their posts. Eventually, Google plans to incorporate features of Google+ in its other services, such as its YouTube video site.

Google+ took only 16 days to reach 10 million Users.Here is the graph with stats of google+'s rivals.

 

Still, the growth of Google+ has impressed observers because access to it is by invitation only, meaning people can join only if a current member invites them. And the company hasn't yet marketed the service to the more than one billion monthly visitors who use its search engine, Gmail and other services.

Here is Time to reach 20 million Users:

Google has a long way to go to reach the scale of Facebook Inc., which has more than 750 million users, and Twitter Inc., which has more than 200 million registered accounts.and I believe that Google will hit 100M users inside of three months  If you agree hit +1, if you disagree post why.
