Wow. I love the concept, but this is not trivial. What about spelling mistakes? What about location (if there are multiple versions of a restaurant -- which one is used? What if your friends have entered in information for multiple locations of a restaurant)? What about text that only SOUNDS like its a restaurant -- and yet I get ratings for it. Also -- what if I only want to share this information with a few friends, not random strangers that happen to know my number? This sounds like a huge potential for unwanted information leak.
