Google Social Network Attacks Facebook And Foursquare : Zennie Abraham : City Brights | The Google+ Project | Scoop.it
The problem is that Google didn't think about how the "circles, hangouts, Instant Upload, Sparks, and Huddle," all fit together, or about what really binds people to each other. Google's system connects people but it does not let me see what people - my friends - are doing.

People like to know what other people are doing. Facebook's News feed allows that, even more than the status updates. Google should find some kind of way to incorporate Facebook's user experience into the Google Social Network, or else, it's just not going to catch on with many other than early responders.
