For years, as the popularity of Facebook has exploded as not only a space for sharing enviable photos of your beach vacation but also as a place to vent about current events, mourn the loss of loved ones, and discuss our ever crumbling world, users have complained that the "Like" button is inadequate as a sole option for reacting to others' posts. CEO Mark Zuckerberg has maintained that the social network should be this place of boundless positivity, and not a forum for up-voting and down-voting like Reddit — even insisting as recently as nine months ago that Facebook would never have a Dislike button. But he's turned tail, and as he announced in a Q&A today, Facebook will, finally, be getting a Dislike button.

As Business Insider reports, the revelation has been hard won for Zuckerberg, who now realizes, at long last, "What [people] really want is the ability to express empathy. Not every moment is a good moment."

Zuckerberg, whose ideas about other people and the world at large are not often especially empathetic, or intellectual, says the feature will be launching on the site soon, but adds that, "It’s surprisingly complicated to make an interaction that will be simple."

The move comes after some particular backlash over Facebook's we're-all-happy-here tone-deafness following the rollout of their Year In Review feature in December 2014. Writer Eric Meyer wrote an essay about being faced with his own Year In Review photo montage, which concluded with the standard "It's been a great year!" but which centered on photos of his young daughter Rebecca who died last year on her sixth birthday. He, rightfully, called out the "inadvertent algorithmic cruelty" of the feature's programmers, saying that the design, which neglected to allow users to opt-out before it was displayed, was made solely for "the ideal user, the happy, upbeat, good-life user," ignoring the (vast majority of) people whose years might not have been "great."

Likewise (ahem), those announcing the deaths of parents, spouses, pets, or even fires that destroyed their homes, may understand that the "Likes" their posts get are not expressing happiness over their loss. But Facebook itself has not allowed us an option outside of comments for expressing anything more complicated than a thumbs up.

Facebook Likes, meanwhile, like retweets, have become the simplified means through which we share and "up-vote" the news of the day, which will complicate matters when the site implements a button that expresses the opposite, or multiple buttons.

In a Q&A from last December, Zuck suggested that in addition to disliking, they may be instituting buttons that express a somewhat bigger range of emotions, "but we need to figure out the right way to do it so that it ends up being a force for good, and not a force for bad and demeaning the posts people put out there."

In any event, we should probably celebrate this day when Mark Zuckerberg finally acknowledged that all the world is not worth liking.
