Last night, Facebook rolled out its latest edition of the constant stream of updates from all of your friends you don't really keep in touch with News Feed, complete with a real-time, scrolling update box on the upper left, the introduction of user-determined "top" stories, and an annoying box for new people you should "subscribe to" (still figuring that one out).
Its membership has since grown, people keep uploading pictures, and you're still logging in every 5 minutes to see the latest update from all of your co-workers and high school friends.
