Will "Haha" and "Sad" be used for negativity and trolling?
It’s nice to encourage people on the Internet to be more empathetic, but the world wide web is an unruly, troll-packed wasteland that can’t have nice things. That's why Facebook never gave us a Dislike button before -- there's a good chance the whole operation will be swiftly co-opted and fall victim to the kind of hatemongering you see on Twitter. Imagine a scenario in which a teenage girl posts a new photo of herself. Maybe it gets a bunch of Hearts and Likes, but pepper in an ironic "Haha" or "Sad" and you’ve just discovered a fresh way to screw with someone's head.
What if Reactions fail? Will Facebook retract them?
Facebook users come in all shapes and sizes, but there’s one thing that unites us all: laziness. And thanks to autoplaying videos and instant articles, Facebook is only perpetuating our desire for instant satisfaction. So Facebook's attempt to compel us to go above and beyond and, gasp, think about how we feel, let alone make the extra click to let people know, is pretty damn ambitious. If it turns out Reactions suck, will they admit it and issue a do-over?
