Update: Discussion has moved on to a new thread.
The hiatus is over with today's publication of chapter 73, and the previous thread is approaching the 500-comment threshold, so let's start a new Harry Potter and the Methods of Rationality discussion thread. This is the place to discuss Eliezer Yudkowsky's Harry Potter fanfic and anything related to it.
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. The fanfiction.net author page is the central location for information about updates and links to HPMOR-related goodies, and AdeleneDawner has kept an archive of Author's Notes.
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Eliezer Yudkowsky which is not supposed to be publicly available (which includes public statements by Eliezer that have been retracted).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.
Nitpicking on chapter 74: (1) No one in the UK would be likely to use the word "gotten". (2) Surely Tracey should say "mundata sum" rather than "mundatus" since she's female? (Yeah, it's a quotation. But the person being quoted was male, no?)
This fic is written in American English, Eliezer isn't even remotely trying to be British (look t.e. at all the -ize verbs).
I do think it was a wiser choice than attempting to fake Old World speech, but now that HPMOR has become extremely popular I REALLY wish he would enlist some native fans to Britpick the chapters. I'm not even British and I still found it quite jarring when Quirrell retorted "Fire me" instead of "Sack me".
