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 87. The previous thread has passed 500 comments.
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, 14, 15, 16, 17.
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Eliezer Yudkowsky which is not supposed to be publicly available (which includes public statements by Eliezer that have been retracted).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.

Some points from earlier chapters that remain unclear to me: any insights would be appreciated?
1) Why did Neville's remembrall go off so vividly in Harry's hands? Also, how are there now two remembralls?
2) Do we have any more information/guesses about Trelawney's prophecy that Dumbledore cut off? What starts with 'S'?
3) Who told Harry to look for Hermione on the train? The writing is ambiguous, and it's not really clear why McGonagall would've wanted them to meet. I guess other theories are worse, though.
4) What's up with Harry's father's rock? Just a way for Dumbledore to encourage Harry to practice transfiguration?
5) Why are we so sure Dumbledore burned a chicken (or transfigured something)? His explanation makes total sense, and Harry's confusion at the time is well-explained by his lack of familiarity with phoenixes. It seems more reasonable to assume almost-burned-out phoenixes look like chickens than...whatever the alternative is.
6) Who is saying "I'm not serious" in Azkaban?
7) Is the "terrible secret" of Lily's potion book really that Snape and Lily fought about it? That just seems like a bizarre reason for a friendship to end. Were Dumbledore's suggestions incorporated into the potion Petunia took?
8) Why did Quirrell leave a polyjuice potion in Bellatrix's cell? (especially since the crime was meant to go unnoticed)
(8) is because he knew that the moment Dumbledore learned of the potion, he would conclude that Harry Potter was not the mastermind of the escape. "to fathom a strange plot, one technique was to look at what ended up happening, assume it was the intended result, and ask who benefited."
