(The HPMOR discussion thread after this one is here.)
This is a new thread to discuss Eliezer Yudkowsky's Harry Potter and the Methods of Rationality and anything related to it. There haven't been any chapters recently, but it looks like there are a bunch in the pipeline and the old thread is nearing 700 comments. The latest chapter as of 7th March 2012 is Ch. 77.
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.
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.
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:
You do not need to rot13 anything about HP:MoR or the original Harry Potter series unless you are posting insider information from Eliezer Yudkowsky which is not supposed to be publicly available (which includes public statements by Eliezer that have been retracted).
If there is evidence for X in MOR and/or canon then it's fine to post about X without rot13, even if you also have heard privately from Eliezer that X is true. But you should not post that "Eliezer said X is true" unless you use rot13.
Harry and co. have one untapped potential ally: Lucius Malfoy. If they gave him all their clues, he may be convinced, just as they have been. And he has a powerful motive to find out who really tried to kill his son, even if he goes through with the trial against Hermione to avoid losing face.
The problem is how to approach him. He would not trust Dumbledore (his political enemy), Harry (he believes he is Voldemort and will soon hate him for 'turning' Draco), or Snape or Minerva (Dumbledore's agents).
I nominate Quirrel (to be sent by Harry) - known (or at least publicly displaying himself to be) free of Dumbledore's influence, a powerful Slytherin, and the one who actually saved Draco's life. Lucius would listen to him. Whether Quirrel would want to cooperate is another matter, but he should have some difficulty saying no to Harry and Dumbledore at once.
For Lucius to trust them, some of them might have to volunteer to testify in front of him under Veritaserum that they really believe the theory that Hermione didn't do it. Dumbledore is a known Occlumens, Snape and Quirrel would at least be suspected of being such, Harry told Draco he is so now Lucius knows as well. A weaker character like Minerva would be useless because Lucius could easily believe Dumbledore misled her. This is a problem...
Lucius would obey a direct order from Voldemort, I should think. Maybe not from Harrymort, but if Quirrell could reveal himself...
