Update: Discussion has moved on to a new thread.
The hiatus is over with today's publication of chapter 73, and the previous thread is approaching 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 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. 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Eliezer Yudkowsky which is not supposed to be publicly available (which includes public statements by Eliezer that have been retracted).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'd like to warn of a slight ambiguity in the stated commitment Eliezer made in this latest chapter. I'm especially worried that since money are involved, some people may feel cheated if the pledge isn't clarified ASAP and it ends up being the weaker form of the pledge.
"I will release completed chapters every X days" -- does it mean that the chapters that are currently completed, will be released one every X days? How many chapters are those? Or does it mean Eliezer pledges to complete and release a chapter on such a schedule for the remaining duration of HP:MoR?
If it's the stronger form of the pledge, I doubt anyone will complain -- though I'm a bit skeptical that it's wise to make a promise as hard as "a chapter every three days".
For some reason I interpreted the commitment as lasting until the Singularity Summit. I have no idea how that happened though, there's not really anything in the language to suggest that.
