You post a topic, list, category, whatever, in my comments section (Top Five People I'd Like To Kill, Top Five Musical Pieces Ever Written, etc.). Then, in a separate post, I'll post the answers to all your Top 5 ideas, according to me. Then you post this offer in your own journal.
I make no promises as to the quality of any of these lists...just so you know.
EDIT: Aaaaaaand as you can see, I'm not bothering with the separate post. Here and now, baby!
