Bunch of reactions to the new chapter:
I sort-of guessed the solution! squee I don't usually like to speculate on what's going to happen in works of fiction, because if I'm wrong I'm embarassed and if I'm right it lessons the surprise. But I had fun speculating and the chapter still had me on the edge of my seat with the tennis match of negotiations.
Professor McGonagall is so damn awesome.
The bit with the dementor was hilarious, but I don't really understand this section:
The Dementors are Death, and the Patronus Charm works by thinking about happy thoughts instead of Death.
If Harry's theory was correct, that one sentence would be all it took to pop the Aurors' Patronus Charms like a soap bubble, and ensure that nobody within reach of his voice could cast another one.
Why, even if Harry's theory was true, would the animal patronuses not work once people know the truth? Even when you know death is bad, you can still think about other things.
Suppose I offer to give you a dollar unless you think of how many letters are in the word "cat".
Could you do it?
Now replace "give you a dollar" with "not kill you horribly" and replace "how many letters..." with "your own inevitable mortality". The stakes are even higher and it's effectively the same task, but the problem sounds even harder...
(of course, that may just be my own mind projection fallacy at work. Did anyone make it to the end of this comment without thinking of the number "three"?)
The new thread, discussion 13, is here.
This is a new thread to discuss Eliezer Yudkowsky's Harry Potter and the Methods of Rationality and anything related to it. With three chapters recently the previous thread has very quickly reached 1000 comments. The latest chapter as of 25th March 2012 is Ch 80.
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, eleven.
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:
