Is it really that important that you use your 2000th post on something good? I dont pay attention to my post count or post average, I just pay attention to the subject that I'm discussing about.
This is a website after all, and it doesnt really matter in real life what level, how many posts, or anything else you have. (except for flashes and music maybe).
All that matters to me is how good a person's ability to apply to a conversation.
