About Google +

Google + (Plus) is a Multilingual Social Networking and identity service woned and operated by google inc. It is the second largest networking site in the world. It has approximately 359 million active users. As of May 2013, It had a total of 500Million registerd users, of whom 235 million are active in a given month.

Google Launched the Google + service as an "field test" on June 28, 2011, but soon suspended early invites due to an "insane demand" for few accounts. On August 6, each Google + member had 150 invitations to giveout until September 20, every one 18 years of age or older without the need for an invititation. Google + is available as a website and on mobile devices. In the "stream", this occupies the middle of three colums of the page, users see updates from those in their Circles. There is an input box which allows users to enter a post.

Along with the text entry field there are icons to upload and share photos and videos. "Circles" enable users to organize people into groups for sharing across various Google Products and services. Although other users may be able to view a list of people in a user's collection of Circles, they cannot view the name of those Circles. "Hangouts" are places used to faciliate group video chat (with a maximum of 10 people participating in a single Hangout at any point in time).

Only Google + users can join the "Hangout" if they happen to possess the unique URL of the Hangout. "Messanger" is a feature  available to Android, iphone, and SMS devices for communicating through instant
messaging within Circles. "Instant Upload" is specific to mobile devices, it stores photos or videos in a private album for sharing later.
