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:
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Eliezer Yudkowsky which is not supposed to be publicly available (which includes public statements by Eliezer that have been retracted).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.
You're assuming that Quirrellmort succeeds in his plan, and succeeds without major hitches. The hitches, and/or Harry's final victory, are where the twists and turns come from.
At this point, everybody who knows Voldemort's back and isn't named "Harry" has Quirrell as prime suspect. What happens when they actually pursue him?
Beyond that we still have both the Deathly Hallows and the Philosopher's Stone as major artifacts that the story has made a big deal of that haven't been fully put into play. Notice how almost everybody who talks about Harry's cloak of invisibility has something to say about it being the Cloak of Invisibility?
So if the author wants twists and turns, he's put in the setup for them.
The final ending of Lord of the Rings was declared in about chapter 2 of the book - "look, someone puts the ring in the fire, all right?"
Books are not exciting because the ending is completely surprising; books are exciting because even though you know the ending, getting there turns out to take all kinds of shenanigans.
And I think HPMOR is doing pretty well so far on the shenanigans count.
This has already played out, in that the cloak turned out to make people invisible to Dementors and also protect them against the Dementors' influence. Also, Harry has "mastered" the cloak in the sense that he can now see other people while they are wearing it. And the idea of it being the cloak is simply taken from canon; people's reactions have just been slightly adjusted for realism.
On the other hand, we suspect that Quirrel has another Deathly Hallow, the Resurrection Stone, and that hasn't played out yet.
