The new discussion thread (part 15) is here.
This is a new thread to discuss Eliezer Yudkowsky’s Harry Potter and the Methods of Rationality and anything related to it. This thread is intended for discussing chapter 82. The previous thread passed 1000 comments as of the time of this writing, and so has long passed 500. Comment in the 13th thread until you read chapter 82.
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: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13.
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Eliezer Yudkowsky which is not supposed to be publicly available (which includes public statements by Eliezer that have been retracted).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.
Did anyone notice the bit about the Philosopher's Stone? I had initially assumed that the PS was following canon, and the reason that the PS remained intact in Hogwarts was that Voldemort made no attempt on it and bypassing the incredibly elaborate protectings (per book 1) prompting its destruction by Dumbledore & Flamel.
But now we have Harry suggesting it be moved, Dumbledore agreeing and it not being moved because Flamel wants it at Hogwarts. Well, in book 1 when they discovered it could not be kept safe at safest place #2 (Gringotts) they moved it to safest place #1 (Hogwarts) and when safest place #1 failed, they just destroyed it. Dumbledore breathes no word of destroying it, despite both him and Flamel consenting to it in canon.
And notice, if you check MoR carefully, at no point is Harry aware that the guarded object is the Stone; nor has Flamel been mentioned anywhere near Harry as creator of the Stone - Flamel has only come up in conversations with Dumbledore/McGonagall/Snape/Quirrel. (Although the topic is one would expect to be of keen interest to Harry: the Stone, recall, grants immortality or at least anti-aging.)
Conclusion: Eliezer has diverged from canon and carefully kept Harry ignorant because the Stone is going to play a role in future plot events. Given its properties, probably a large role - it's now a massive Chekhov's gem.

Ever since I read the Potter books, I knew that the Philosopher's Stone stood a very high chance of being MoR!Harry's weapon of choice.
(Yes, I read the actual Potter books for the first time after reading the first few dozen chapters of MoR.)
