That Reddit post is funny but the truth is, they're right, bitching about things online is a form of addiction. I have a friend from high school whose online persona is so awful I stopped following him. I'll go to his house and eat with him and he's mostly a normal person, not the insult machine he plays in social media. But occassionally he snaps in real life as well. I'm not sure he can tell the difference between trolling someone or real anger anymore.
