Why do I blog?

I blog because someone else thinks it is important. I blog because my grade depends on it. I blog because I have to. Do I WANT to blog? NO. Why not?
Why do I want to post my thoughts for virtual strangers to read and dissect? I may be a people person, but I read faces when I talk to people. I don't like email much, because I still can't see the people with whom I speak. And do you know how easy it is to be misunderstood in writing? (That is a rhetorical question.)
