Facebook is squarely at the center of this new universe, and much of what people do online these days starts there. But Facebook's masterstroke has been to spread itself across the web and allow others to tap your network of friends. As a result, thousands of websites and apps have essentially become satellites that orbit around Facebook. You can now go to Yelp to find out what your Facebook friends say about the new coffeehouse down the street, visit Spotify to let them pick music playlists for you, or play Zynga games with them. To make matters worse for Page, much of this social activity can't be seen by Google's web-trolling algorithms, so every day they (and by extension, Google) become a little bit less accurate and relevant.
