text: Putting up Ads that is based off your emotion is not a smart idea to me. So if im angry im most likely will have a negative vibe and if you put something up that is close to be negative its not going to make me happy. If I am in a good mood more than likely I would not want to see no Ad. Then there expression is compared against a neutral face, some people just look naturally mad. If some one regular face looks mad then how would it read ther face then, that person could be happy.
