Update: Discussion has moved on to a new thread.
The load more comments links are getting annoying (at least if you're not logged in), so it's time for a new Harry Potter and the Methods of Rationality discussion thread. We're also approaching the traditional 500-comment mark, but I think that hidden comments provide more appropriate joints to carve these threads at. So as of chapter 67, this is the place to share your thoughts about Eliezer Yudkowsky's Harry Potter fanfic.
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. The fanfiction.net author page is the central author-controlled HPMOR clearinghouse with links to the RSS feed, pdf version, TV Tropes pages, fan art, and more, 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Eliezer Yudkowsky which is not supposed to be publicly available (which includes public statements by Eliezer that have been retracted).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.
Something I've mentioned before, but usually as part of a reply to something else: I strongly believe that the work would benefit from being officially divided into different books. Chapter 63 was incredibly cathartic to read, partly because it was a very intense chapter that resolved a lot of stuff, but partly because at the time, we knew a hiatus was coming and that it was the End™ of a particular section. That, in combination with the fact it touched upon every single plot thread, made it feel more potent. And the PDF version, at that time, was a little over 1000 pages, which is about right for a Harry Potter book.
It's also a daunting to get new people to read something when there's a bajillion chapters. I don't know if you're planning for two parts or three, but presumably there will be at least 120 chapters when this is done, if not 180+. I had better luck getting new people to read it when I specifically said "book 1 just finished, I can give you the PDF of that," and I think that's in part because "one book" is a friendlier way of measuring length than some large number of pages.
Fanfiction.net might have specific rules, or you might want to just keep things consistent there. But I'd like it if when the next section is finished, you do a PDF that gets treated as its own separate book.
(I also feel like Part I could benefit from being divided into subsections. For instance, the first 20ish chapters end with Harry sending the letter to his parents, which felt like a good stopping point, as did the Christmas break which gives us a pause before the events leading to Azkaban kick into overdrive. I'm less concerned about that, but I do feel like having discrete chunks to show to people makes it less daunting to begin reading).
To go with the TV series analogy proposed by Eliezer, maybe it could be an end of Season 1?
