"While Facebook could implement a similar type of rating system, Facebook’s rating system of Likes is an absolute one that cannot differentiate between something that is liked and something that is liked a lot, this hindering the value proposition and usefulness especially in large groups." Facebook already offers a star rating system for businesses/locations/Pages. They display your friends' ratings when you visit a page, post your new ratings in friends' News Feeds and occasionally display a widget enticing you to rate places you have visited. It would seem not too out of the ordinary for facebook to in some way display links to or ratings for businesses you discuss in Messages. I'd be surprised if they hadn't experimented with that.
