ETA: There is now a third thread, so send new comments there.
Since the first thread has exceeded 500 comments, it seems time for a new one, with Eliezer's just-posted Chapter 33 & 34 to kick things off.
From previous post:
Spoiler Warning: this thread contains unrot13'd spoilers for Harry Potter and the Methods of Rationality up to the current chapter and for the original Harry Potter series. Please continue to use rot13 for spoilers to other works of fiction, or if you have insider knowledge of future chapters of Harry Potter and the Methods of Rationality.
A suggestion: mention at the top of your comment which chapter you're commenting on, or what chapter you're up to, so that people can understand the context of your comment even after more chapters have been posted. This can also help people avoid reading spoilers for a new chapter before they realize that there is a new chapter.
This could be a situation where nobody really likes the outcome, but (since it was obviously a very fair punishment) they all treated it with respect (wanting to signal that they liked it). So nobody suggested anything really exciting, figuring that nobody else would go along with it. (There's a name for that fallacy of decision, where everybody votes for their second choice to be nice, since they think that it's the first choice of everybody else.)
Or else, they each had a secret plan (to summon Harry to their arms).
