“Graph Search lets Facebook users enter phrases like “sushi restaurants my friends like” or “dentists my friends like” and reveals all their friends’ favorite local spots. Another new Facebook tool, Nearby, functions very much like Yelp or Google+ Local and makes it easy for consumers to find local businesses recommended by friends. These tools reinforce one of the main reasons that social media is more powerful than other forms of advertising: It surfaces valuable friend-to-friend recommendations of local businesses.”
