Did a post purporting to solve the decision theory by srn347 just vanish from the forum, including all the comments? I thought one cannot delete other people's comments.
This being possible is a known bug.
(I saw a cache of the post on Google Reader; it was a well-known observation elevated to the status of an all-powerful epiphany, and the post was also probably an early draft, since it was missing details mentioned at the beginning, which might be why it got deleted or hidden by the author.)
If it's worth saying, but not worth its own post, even in Discussion, it goes here.
