O.K. I will try and translate this post/hour business into something everyone can understand.
When I first learned about the contest I picked a moment in time and recorded the official post count at that time.
That time was 12:52 PM on 6/10/10. At that time there were 1,984,839 posts.
From that point forward I began to track the posts per hour in an attempt to better estimate the time of the 2,000,000th post.
Below is a list of members and their estimates translated into posts/hour based on that starting point. (I've narrowed this down to those estmates that fall between 6/24/10 and 6/27/10 as these are most probable at this point)
