Post titles

I'm toying with the idea of losing the title field on my posts, because:

1. I have to think up something;
2. The title takes longer than the post;
3. Short posts don't need a title;
4. Especially not a lame play on words, or a palindrome, like Notlob;
5. Kottke doesn't have titles, and nor do UV and Pillock.
   

What do users think? Do you GAF? Would it affect your Graping experience? Are you bovvered tho?
