I post if and when I want to, I'm not bothered with the number of posts I or anyone else has posted. I know I've posted alot, but I don't aim to reach any particular mark, nor am I in some competition with someone as to who posts the most. That's why I rarely ever post in threads where someone has become a "Jedi" or "Emperor" - posting numbers don't mean anything to me. The only time I'll look at the number of posts a person has made is when I see a name I haven't seen before, and I look to see how long they've been here and how much they've been involved with the site.
I find the dates interesting, because it give some idea how long a person has been associated with the board.
LOL @ Irongland - btw, I don't drink coffee, so if I win, can I have a milkshake maker?
