Why does one blog?

I've noticed recently that many people I know will actually tell you they have a blog and that they blog, but upon going to their actual blogs one could note that they have blogged, but currently are not doing so. I too am guilty of the blogger bug, but note... I have not blogged since June. In fact, I have two blogs and I haven't blogged on either on since June.

So this made me ponder... why does one blog?
(In the spirit of Dave)

THE TOP TEN REASONS WHY PEOPLE BLOG
10. To share information that you think others may be interested in. (you are so fooled)
9. To share information that others have already shared.
8. Because your boss tells you to and you get paid for it.
7. To practice your writing skills.
6. Because you travel and you keep losing your travel journal.
5. To let your family know that you are still alive.
4. To be heard because no one ever listens.
3. In a nerdy world it is uncool not to have a blog.
2. People don't have lives so they create their own virtual life.
1. They want to get a hard bound book published in the real world.

At any rate, maybe I should put it in my PDA as a reminder that I should blog on a more regular basis because I really don't think I have the right to say I am a blogger and not just tell people, "I have a blog."
