Social Graph API: One small step for Google, one giant step for the Internet Operating System
But a real platform service makes it possible for developers to do things entirely outside the realm of the originating provider's application. Unlike OpenSocial, which I found disappointing, the Google Social Graph API is a game-changing play in the social networking space. It's a huge step towards open standards and a level playing field in smart social apps, and exposes Google's data and infrastructure in a subtle and powerful way. I can't wait to see what comes next!
