Is that this person did the following only:
Hit the main page.
Created a new user.
Hit the Water Cooler Forum.
Hit the root post in this thread *only*.
Added the response.
That's it. The user 1) knew exactly where he was going and 2) was here explicitly to add that response.
He didn't look at ANYTHING other than what was necessary to create the post.
Oh... some interesting name lookup information on his IP address:
adsl-65-64-153-148.dsl.stlsmo.swbell.net
In other words... it is someone who had been here as a user already and it is someone who lives in St. Louis...
