Google has started a new project call Google plus which directly targeting Facebook users. This is not the first attempt of Google to gain the territory of Facebook, Previously Google Wave and Google Buzz were launched but they were not effective in capturing the grounds of Facebook.
Under the Google plus it has introduced new functions such as Circles, Hangouts, Huddle, Sparks. All though the names are new to the social networking domain the functions behind these names are much more similar to Facebook.
Still this project is in development stage and Google have given a sneak peak about it's development under https://plus.google.com link. So we will have to wait till Google plus is released to public and time will tell who will be the leader of social networking in cyber world.
