The post and thread count is very deceiving. There are tens of thousands of posts that show nothing at all after you go beyond two years.
Perhaps you could prune them (its easy with a SQL statement on NULL posts_text) and then run a simple SQL Count to display the real thread an post counts.
We're Packers fans, we shouldn't be lying about things like this!
