I never really did care about post counts, though I used to have around 40+ post per day back in the first ~2 months when I joined.
Once I lost around 400 posts due to a rollback, but hey, nobody really looks at your post count anyway.
I actually care about my post count because the more you have the less likely you are to be called a newbie.I don't really mind having my old avatar back though so I am not too mad about this.
