Mark Zuckerberg confirms Facebook are considering a 'dislike' button

How often have we wished that there was a 'dislike' button on Facebook? For those times when liking a post seems inappropriate but you still want to signal that you've read, acknowledged and empathised a friend's bad news - or just to express your disapproval of a video, post or pic.
Yesterday, at a Facebook Q&A event in California, Mark Zuckerberg confirmed that they were considering bringing in a 'dislike' feature on the site.
"A lot of times people share things on Facebook that are sad moments in their lives or are tough, cultural or social things and often people tell us that they don't feel comfortable pressing 'like' because 'like' isn't the appropriate sentiment when someone lost a loved one or is talking of a very difficult issue,” he said.
“We're thinking about it. On the dislike button... there are more sentiments that people want to express than just positivity or that they like something.”
Their main concern is, of course, that people would abuse the feature and it would end up "demeaning the post that people are putting out there".
We can definitely imagine people gettiing passive-aggressive
fast.
