Abstract: A social networking system according to an embodiment of the invention may gather, manage, and order information, such as users' posts. Posts may be organized in objects called “streams” or “currents”, and users may discuss streams, posts, and/or other discussions. The system may keep track of users' actions, and use these actions to score, e.g., posts, streams, discussions, and/or users. In embodiments of the invention, these scores may be used, e.g., for rankings, and these rankings may be used, e.g., to recommend posts, streams, discussions, and/or users to users of the system.
