A long time ago, I wrote a short bit on why I wanted to be able to dislike comments on Facebook (and anywhere else for that matter). In my mind (at the time) I was trying to put across the point that we live in a world where we are not allowed to be negative for fear of offending people.
My vision of a dislike button would have lead to a world where the useless or unhelpful crap that filled much of social media could be slowly trained out. By that I mean that trolls and the like would learn that if everything they post can be disliked and hidden, that they would just crawl away and die.
