This website is very confusing .We only keep on adding in circles.I found this website too boring.Google have closed orkut and come up with new idea google plus.But they fail to attract customer.
It is also connected with android mobile. Worst part is if your auto update otion is on it will take all your video and image of your phone to google plus.It has uploaded all watsapp video. This is the default setting.
For promotion its good as lot of people are using it.
