Facebook’s Graph Search Is Here. Check Your Privacy Settings.
Facebook on Monday turned on “Graph Search” for all English-speaking users in the U.S., expanding a test program it rolled out in January to tens of millions of users.
The tool allows people using natural-language searches to find nearly anything indexed on Facebook — “photographs of friends before 1999″ or “restaurants in San Francisco” — giving them another reason to share information and spend more time on Facebook. It’s also another reason to double-check your privacy settings.
