There seems to be an inverse correlation between how much Eliezer likes his chapters and how much I like them. (My favorite chapter is 47)I thought 75 was great. No, it wasn't as funny. It was chapter 74's job to be funny, and chapter 75's job to touch on some serious issues, and that doesn't make it worse.
I really liked Hermione and Harry sitting and talking through their issues in an adult manner. Literature could use more of than and less indignant yelling like the fourth-year-girls recommend.
(In general I also like chapters with lots of dialog. I feel like we get the most character-development-per-pound that way.)
I just like how often not communicating is used in fiction as a false way of creating conflict, but Eliezer shows that you can still have a story (with conflict!) when people try and understand each other.
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:
