I was seeding printed copies of that around my college campus for a little while.
It is interesting that you note the articles get creepier as the numbers get higher; I think that's because of the changing site culture over the years. The pre-1000 slots were all filled back when the site had a slightly more light-hearted, relaxed tone to it; you got iconics like 173 and 682, but you got sweet things like 085 and 131 too. Now 'goofy' articles, and things that could be useful or beneficial, get downvoted, filtering out the really creepy ones.
I would disagree with Keter = creepier, though. Sometimes, destroying the world isn't creepy at all; i.e., the Keter Cakes and the Keter Spaghetti.
