I can't create polls on a free account?

Well, I guess I'll just depend on your comments...

What do you feel I should best use my LJ for?

1) My moments of whining (and my personal life);
2) My professional progress (on literature, music, gaming, etc)
3) Professional announcements (turn the blog into my newsletter, if you will)
4) Mix and Mash
5) Memes
6) Your own answer (in comments)

Thoughts?
