For a long time search has been about you and nothing but you. When you go to Google, Bing, Ask or any of the other search engines they only take into account what you, and you alone, are concerned with. Type in a keyword or two, or three and the results returned will be based pretty much on that scant amount of text. In some cases this can be enhanced by letting your past search results influence what you are looking for now, but the emphasis is largely on the individual. All that is about to change. Both Google and Bing are starting to develop ways to make your social context influence the results you are sent.
