Yesterday, after some digging, we were able to confirm that the internal codename for Google's upcoming social project is "Emerald Sea". Despite some confusion that it may be called "Emerald City", it is definitely "Sea", we've confirmed with several sources. But there's more. As one of our sources told us yesterday, these codenames quickly evolve. And in fact, it now looks like Emerald Sea may already be a slightly older name. And Google may be close to picking the final name for the product. As of right now, we're hearing it's being called "Google +1" or "Google Plus One".
