Sure "National D. A. R. E. Day" means that the politicians who created the day believe that drugs exist and likely they regard them as bad. That D. A. R. E. actually exists means there is a wide community of people that believe or act like they believe likewise. If this was the ONLY evidence of drugs existing I would have reason to be skeptical of the existence of drugs.
Really most any single artifact of a wide phenomenon, taken completely in isolation, would be only weak evidence of the phenomenon's existence. Drugs, Jesus, Dark Wizards, Ghosts or Gravity, I think if we only saw one of the many effects that each predicts then we would have a good reason to doubt the reality of the phenomenon. Therefore I now believe it was unwise of me to take your comment that singled out one artifact of the Voldemort phenomenon (the holiday) and point out that taken by itself it was not strong evidence of his existence. Looking at it now, my comment appears to have the structure Daniel Dennett calls "a deepity": in so far as what I said was true, it was trivial and in so far as what I said was profound it was false.
The new thread, discussion 13, is here.
This is a new thread to discuss Eliezer Yudkowsky's Harry Potter and the Methods of Rationality and anything related to it. With three chapters recently the previous thread has very quickly reached 1000 comments. The latest chapter as of 25th March 2012 is Ch 80.
There is now a site dedicated to the story at hpmor.com, which is now the place to go to find the authors notes and all sorts of other goodies. AdeleneDawner has kept an archive of Author's Notes. (This goes up to the notes for chapter 76, and is now not updating. The authors notes from chapter 77 onwards are on hpmor.com.)
The first 5 discussion threads are on the main page under the harry_potter tag. Threads 6 and on (including this one) are in the discussion section using its separate tag system. Also: one, two, three, four, five, six, seven, eight, nine, ten, eleven.
As a reminder, it's often useful to start your comment by indicating which chapter you are commenting on.
Spoiler Warning: this thread is full of spoilers. With few exceptions, spoilers for MOR and canon are fair game to post, without warning or rot13. More specifically:
