Google now has a hidden function with which the user can search for people's faces. By typing "&imgtype=face" behind the URL of the search results, Google will only show you faces. Who is looking for Johan Cruijff then doesn't get the Johan Cruijff cup, soccer fields, books, cars and other Johan Cruijff related things, but only faces. In the results you will also get faces of other people, but this is a good filter again (dc, Dutch).
This way we get better answers to the questions we ask. In the near future our question "I'm looking for a picture of Johan Cruijff" will be analyzed to: Johan Cruijff -> personal name. Picture of personal name -> picture of face. After that face recognition will be applied (Google bought face recognition specialist Riya back in 2005). For well-known people a database like Wikipedia will be consulted. For unknown people all pictures will be compared to each other, and the most likely person will be shown. After that, social coaching brands will search for names we know. There will probably be thousands of men named Jan Jansen, tens of thousands named John Smith, and maybe hundreds of thousands named Li Wang (in China there are only 100 surnames). An individual person however probably only knows one or two of them at the most. Social coaching brands will know exactly who we want to see, and will find the right pictures of these people right away. Google has laid the foundation to make this possible.
