Facebook is about to get a "dislike" button, but it will not be for putting down content that users dislike.
Instead, the button will be a way for people to express empathy, co-founder of the social network Mark Zuckerberg said in a Q+A session held at Facebook's headquarters in Menlo Park, California, on Tuesday, according to a BBC report.
He said Facebook was "very close" to having it ready for user testing.
A "dislike" button has been constantly requested by some users since the introduction of the now-iconic "like" button in 2009.
"People have asked about the 'dislike' button for many years," Mr Zuckerberg, 31, told the audience.
"Probably hundreds of people have asked about this, and today is a special day because today is the day that I actually get to say we are working on it, and are very close to shipping a test of it."
However, he went on to say he did not want it to be a mechanism with which people could "down vote" others' posts.
Instead, it will be for times when clicking "like" on "sad" posts felt insensitive.
Professor Andrea Forte, an expert in social and participatory media at Drexel University in Philadelphia, said users will not suddenly turn on each other's posts, reported the BBC.
In an e-mail, she wrote: "They may use a dislike button to express some negative emotions (like frustration with ads popping up in their feeds) but I doubt it will cause them to start wantonly disliking pictures of their friends' babies, dogs, cats and cooking experiments.
"I suspect it will mainly be used to express mild disapproval, or to express solidarity when someone posts about a negative event like a death or a loss."
