EDIT: New discussion thread here.
This is a new thread to discuss Eliezer Yudkowsky's Harry Potter and the Methods of Rationality and anything related to it. With two chapters recently the previous thread has very quickly reached 500 comments. The latest chapter as of 17th March 2012 is Ch. 79.
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.
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Eliezer Yudkowsky which is not supposed to be publicly available (which includes public statements by Eliezer that have been retracted).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 idea that to the best of my knowledge is my own, is that Harry could use the time turner to go back in time, and get Quirrel/Snape/Dumbledore to false memory charm a student to provide crucial testimony clearing Hermoine and proving a plot. Another part that would help would be to present the wands as evidence (not original to me) but to also steal the wands of Draco and Hermoine out of custody using the cloak and tamper with them to remove any evidence if hat and cloak tampered with them.
I'll expand on this with a post attached to my main one since I've discovered that some people don't like long walls of texts, so if you come up with some reason why this wouldn't work check that post first please.
"The boy smiled, now with a touch of coldness again. "Okay, I'll figure out some way to set it up so that it looks like Lord Jugson betrayed his own side." "
I think that the optimal thing for Harry to do would be to plant fake evidence showing that Lord Jugson was the one whom plotted against Draco. The motivation would be a combination of Lucius 'betraying' the death eaters and a desire to see his house rise in power over House Malfoy. All he would have to do would be to go back in time an hour, steal the wands of Draco, Hermoine and... (read more)
