What is Google Plus (Google +) ? you may be confused with this new one, many people who discuss it. Google Plus is a social networking site like facebook. But, according to the news that I heard, that google+ will replace facebook's position as the best social network site. Because google+ has many features that interesting more than facebook.
But until this moment, I still prefer use facebook than google+, because google + loading is very long compared to facebook.
The Features that Google plus released are very sophisticated and a lot. As hangout features (webcam), Huddle, automatic circles, sparks, and others who do not have facebook opponents.
Google Plus developed by the project name "Emerald Sea", this secret project itself takes one more year and led by Google's Senior VP of Social, Vic Gundotra and Google's VP Product of Google Apps, Bradley Horowitz and estimated to cost around 585 million dollars.
Currently Google has members plus nearly 20 million users in the second week after its release. With so many members, admins google plus limit the number of members, and anyone who would join with google plus, it must be by invitation from someone who has been listed in google+ account. so you can not register to google + without any invitation.
