My take is that it is marginally useful for the users. However, this will be incredibly useful for advertisers, and probably good for Facebook profits. Remember, with Facebook, you are the product being sold. E.g. A Japanese restaurant can search for people in downtown Manhattan who like Sushi. Boom, send them coupons. I know this feature is not currently available, but it will be in short order.
