Google is about to launch Google+ to compete with facebook

Google is about to release Google + or Google Plus to compete with the biggest social networking Facebook. In my opinion I think it will be a success, but won't take down facebook that easily. It will take years to do that. 

"Google+ project will feature social circles (+Circles) which allow users to "selectively share with specific groups within their personal network, rather than sharing with all their social connections at once."

Other features of Google+ project will include the ability to video chatin groups, display interests, share content on the go, and other options/features that are similar to Facebook and other pre-existing networks."

What do you think about this?
