No, I searched for him on my own computer and he shows up at the bottom.
I wasn't logged in as him. I don't subscribe to his blog on Google reader or have any social media connections to him. I didn't find the post through a google search. I don't have Google Toolbar installed.
If he shows up at the bottom, that means he did it while logged in (The only way that there would be that big of a disparity. )
