Facebook Set To Introduce The ''DISLIKE Button

                Facebook founder Mark Zuckerberg has said that the social network is thinking about adding a "dislike" button to the site. He said this in a video post made on his page, adding that a dislike button would make sense for instances when users wanted to express themselves but didn't feel comfortable using the like button.
               As an example, Zuckerberg said a dislike button might help users express themselves on a post about a sad event in someone's life. However, he admits it may not be a good idea because a dislike button could become a way for users to be shame others on the site.

What do you think, should there be a dislike button on Facebook?
