After jumping through hoops to get the new Facebook Time Line setup, I don't think Google Plus has a chance. The new Facebook in a word, is the "Shit". Google + will need to step up big time to even come close, as the new FB Time Line has the best of Twitter, Tumblr, and of course Facebook integrated to it.
FB still has some problems, it suggests friends to me and then goes and revokes my friending ability for 7 days for friending someone they suggested as a friend. Kind of kafkaesque. However you can actually get laid through FB, until people are meeting and getting married or having a divorce over google+ it just can't compete with the power of FB.
