Actually post Buzz fiasco, It seem they have taken the best feature of all the worlds, facebook, orkut and enhanced them with additional security and came up with goolge+ .. .Like... Sparks - gathers videos and articles on topics of interests or hobbiesHangouts - lets friends join video chat with multiple people at onceStream section - similar to Facebook's News Feed but you get to decide which circle which feeds of yours.. One can choose to make it available to “all circles” or even available to “extended circles” - which is like outside your circle. This is almost same with all its feature.. you can decide who gets to seem them and unlike buzz the feature is set to high security by default...
