(The HPMOR discussion thread after this one is here.)
The previous thread is over 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 latest chapter as of 09/09/2011 is Ch. 77.
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. 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Eliezer Yudkowsky which is not supposed to be publicly available (which includes public statements by Eliezer that have been retracted).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.
I've been reading a chapter of MoR to my girlfriend every time we go to a park, and we just got up to Chapter 39. Two thoughts:
It's fun to try to imitate a long series of random noises with your mouth alone in a public place.
Sarah's immediate reaction to the first part was "Why doesn't he just ask Harry for a Pensieve memory of his conversation with Lucius? Dumbledore doesn't use notes." I can't see why not either. My first reaction was that Pensieves haven't been referenced in MoR yet and might work differently, but I was wrong; Draco's going to use his memory of Harry's first date to blackmail him.
Maybe he's not ready to ask Harry to offer such a major sign of trust as allowing someone else to put one of his own memories in their pensieve and view it directly?
Also, do we know if more than one person's memories can be put into a single pensieve? Maybe different people's memories can't be mixed.
