20 reasons why:
0. No one reads it.
1. Then I don't write anything.
2. That's because I don't get comments.
3. I don't get any comments because they don't work anymore...
4. Spam was the most annoying thing ever.
5. That's because MovableType is a stack of crap
6. I'd move somewhere else, but nothing 'imports' all my old entries from here to the new place.
7. ...urk... whatever
You get the idea.
