Further evidence for this theory is that H&C is not great at modelling people, and Snape isn't good at mental models of others either.
If you think H&C2 is the same as H&C1 (I do, for conservation-of-detail reasons), Snape is a plausible candidate for competent plotter who isn't Quirrell or Dumbledore. Which isn't to say that there a clear motive in that case either.
The sticking point in my mind is that the groundhogs day attack should have been a lot more efficient if the attacker was a legilimens.

(The HPMOR discussion thread after this one is here.)
This is a new thread to discuss Eliezer Yudkowsky's Harry Potter and the Methods of Rationality and anything related to it. There haven't been any chapters recently, but it looks like there are a bunch in the pipeline and the old thread is nearing 700 comments. The latest chapter as of 7th March 2012 is Ch. 77.
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.
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.
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:
