We recently passed two million approved posts
But there doesn't seem to be a good way to find out which post marked the milestone, and e6's twitter hasn't said anything. Does anyone know?

@AwesomElephants: twitter is not used that much, mostly for notifications for sites downtime.
Also there's literally no way to check what post that was, considering that posts are constantly deleted and restored, meaning that the milestone shifts the moment you get it, counter in front page also ain't accurate as that would be too computionally expensive to calculate for something not important.
