What is Google+:
Google+ makes connecting on the web more like connecting in the real world. Share your thoughts, links and photos with the right circles. Use easy, spontaneous video chat to strike up conversations with as many as nine people at once. Get everyone on the same page with fast, simple group chat.You share different things with different people. But sharing the right stuff with the right people shouldn’t be a hassle. Circles make it easy to put your friends from Saturday night in one circle, your parents in another, and your boss in a circle by himself, just like real life.
