Google already has a social network, they just don't have a name or homepage for it (those are important). Presumably this would tie right into Profiles, Buzz, and Contacts. Google can easily build a social network around Android, I'm not sure why they aren't going that route. They know who you contact most, they know how you contact them. They just need a private version of Buzz and integrate it into Contacts and they'd be a major threat to Facebook.
