Well, isn't that nice! We got a visit a few days ago from someone down at Apple HQ:
Mozilla/5.0 (iPhone; U; PPC like Mac OS X; en) AppleWebKit/420+ (KHTML, like Gecko) Version/3.0 Mobile/1A001a Safari/419.3
Doesn't look like they did much besides check out the front page... but that was nice of them to stop by, don't you think? :-)
P.S. Can you believe that Apple owns the entire 17.*.*.* subnet? Insane.
