Who maintains/pays for the site now? I tried going to the top page, expecting some kind of obituary or explanation as to why the site is still up, but the blurb there makes it sound like Aaron stepped out for a week and will be updating again soon, except for the last updated note in the corner.
I did a whois lookup out of curiosity, but the contact information all refers to contactprivacy.com, which is apparently set up to allow people to register domains privately.
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.
