Today morning when land on Google.com I saw a big blue arrow on its home page. Its nothing but an ad campaign Google started to get more Google+ users.
Till yesterday Google+ was having invitation only subscription facility but is now available to everyone in the world. Google+ is now targeting its 99+ million users who lands on Google’s home page every week. As compare to Facebook (750 million users) Google+ (25 million users last reported at the beginning of August 2011) has less users but it achieved 20+ million user base within few days which is fastest in world till date.
