Facebook is developing the Open Graph to map user interests and connections between users and content across the web. Through plugins like Like and Activity Feed, any website can integrate with Facebook so that user actions are shared to profiles. This will allow for personalized recommendations and experiences based on a user's social graph. However, some privacy and control concerns exist as users may not want all activity logged to Facebook, and companies may not want to lose control over their own communities and user data. Competitors like Google and Twitter may also respond to Facebook's move to integrate more deeply with the wider web.
