One question that has skyrocketed in popularity since the internet became a thing is, "why are people like this?". There is something about being given unlimited access to billions of other human beings in the world and their thoughts that does not seem to do good things for our brain, but we keep on exposing ourselves to it nonetheless.
When you sit down and think about it, it is kind of crazy that we can log on and say pretty much anything to anyone, whenever we want. While plenty of us are sensible enough to keep ourselves to ourselves, that can't be said for everybody. There are some very screwed up people out there, and unfortunately the internet gives them a lot of exposure. As well as this, it is an opportunity to force the rest of us to join in, too. It's hard to look away when the train crash keeps on happening.
