Mark Zuckerberg mulls over ‘Dislike’ button for Facebook
LONDON — Facebook chief executive Mark Zuckerberg has spoken of his desire to provide users with the ability to express a wider range of emotions, hinting at an addition to the existing “Like” button on Facebook posts in his second public Q&A.
Speaking at the company’s headquarters in California, Mr Zuckerberg admitted to concerns that current methods of interaction on the site might sometimes be inadequate.
“A lot of times people share things on Facebook that are sad moments in their lives,” he said. “What’s the right way to make it so people can easily express a broader range of emotions? To empathise?”
A “Dislike” option is the feature most requested by Facebook users, said Mr Zuckerberg, 30, and he did not dismiss the idea altogether, calling it an important area of discussion.
But he also expressed reservations that a button designed to communicate negative sentiment could end up being used in the wrong way and as a means of demeaning other people’s posts.
“We need to figure out the right way to do it so (the button) ends up being a force for good, not a force for bad,” he added.
