If you use Facebook, you know there is a Like button you can click on to show you like, support, approve or think positively of it in some way. There is no Dislike button, probably to keep the social experience positive, among other reasons. However, this lack of a Dislike button isn’t serving the need on identifying true social public opinion on any matter that might be controversial. If all you ever saw were all the people who Liked something controversial, how would you ever know how many people might Dislike it like in a real poll?
