Looks like you're probably right. I googled him and found http://inamidst.com/sbp/, which says "I’m taking care of Aaron’s sites and data, so email me if you have any queries about that."
I initially wondered about it because it was actually really disturbing when I considered the fungible nature of websites and the possibility of someone posting "past articles" as Aaron.
