Facebook might finally give users the ability to “dislike” things. During a question-and-answer session streamed live on Facebook on Tuesday, Mark Zuckerberg said the company was testing alternatives to the “Like” button.
“People have asked about the ‘dislike’ button for many years,” Zuckerberg said at Facebook’s headquarters in Menlo Park, California. “Today is the day that I actually get to say we are working on it.”
