Looks like you were right, nick. We have just 75 posts left to go before we reach 300,000, but I can see that you now have 7 more posts than 30,000. I honestly doubted it could be done, but you proved me wrong.
With just 75 posts left to go, it looks like I might not be around tomorrow to see the 300,000th post. (I'm always online in the evenings.)
