This can be a contender to Facebook. This is an all new concept. Looks similar to Facebook and other conventional social networking sites. The graphical user interface(GUI) is something odd in the flock. May be kinda flash content in the design of the site. Happy that Google is thinking out of the box. I went through the Google plus tour . Here are some screenshots of the same.[slideshow]
The project includes Circles , Hangouts, Instant Upload, Sparks and Huddle. You can get a good idea of the same ., checking out the official tour powered by Google here. You can get updates by submitting your first name and email address in this page.
