(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Eliezer Yudkowsky which is not supposed to be publicly available (which includes public statements by Eliezer that have been retracted).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.
My theory is that Lucius trumped up these charges against Hermione entirely independent of the midnight duel. He was furious that Hermione defeated Draco in combat, and this is his retaliation.
I doubt that Hermione attended the duel; or, if she did attend it, I doubt that anything bad happened.
My theory does not explain why Draco isn't at breakfast. So maybe my theory is wrong.
I am confused about why H&C wanted Hermione to be defeated by Draco during the big game when Lucius was watching. If you believe H&C is Quirrell (and I do): did Quirrell go to all that trouble just to impress Lucius with how his son was doing? That seems like an awful risk for not much reward.
...Followup: Holy crap! I know exactly one person who wants Hermione to be defeated by Draco when Lucius is watching. Could H&C be Dumbledore?
