It's interesting, isn't it? I think 10 to 20 years ago, it was definitely cool to be cruel online. It was probably because anonymity was the norm, and you didn't know who the other person was (and nobody knew who you were). But now that everybody puts their lives online, there's a push to be kinder to each other. I'm not a fan of the reduced anonymity, but it's nice to see everyone try to be a bit less of a jerk.
Edit: Oh yeah, some of us grew up too I guess. I'm in my thirties now D:
