Internet Hate

What, may I ask is the point of internet hate?

So people go onto other people's blogs and post comments that are spiteful, hateful, hurtful and every other kind of -ful you can think of in a negative way.

Then there are people who get online and post stuff on their own blogs that are likewise very un-positive.

What might I ask is the point of that? Is it to stir up trouble? Is it to create controversy and thereby create readers? (I know that for me and a certain other blog I maintain that is exactly the reason, and it works by the way). But if you aren't out to get money, then what are you trying to do?

The person you are typing at can't see you, hear you, smell you and has no idea that you are anyting other than a 3rd grader who got on the computer when mommy wasn't looking. I guess I just don't understand the point of actually being angry at someone you don't know about something that could very well be a fiction.

Your thoughts?
