The most important thing about Google+ is that it integrates from the start platforms that have arisen since the first generation of social media. So Google+ is Facebook-like and Twittery and bloggy in one package.

But I think this means that G+ might not ultimately be the winner here. The things it really has going for it is combining models developed by others. The big winner will come at the very end, when all the small stuff has been created, and it will be service that combines all the features to become the one network.
