Saad notes that in spite of Twitter's efforts to work with all the available services, there's "very strong competition" between them. "Facebook's strategy is to own the social graph," he says, explaining that, if many sites use Facebook Connect, then Facebook stays in possession of user data, and knows what its users are doing across the Internet. "Google is trying to dilute Facebook's power," he adds. Google's service would keep more social information out in the open, where it can be indexed by Google's search engines.

I think it's going to bring us back to square one."
