You're forgetting that Tom Riddle actually did study at the monastery before he destroyed it to deny that training to his enemies.
Voldemort is especially violent and comes off as stupid, but he's just one of Tom Riddle's characters, and if you consider their actions as a whole they're smarter than they appear, on purpose.
There is a classic trick that card counting teams use to avoid detection. If one person shows up, and bets conservatively until the cards are in their favor, and then immediately starts making huge bets, then it is obvious that they are a card counter and the casino can throw them out. But, if that one person betting conservatively simply leaves the table once he thinks the deck is in his favor, and then someone else comes in wearing a loud Hawaiian shirt and acting like a "wild and crazy" risk-lover, then it just looks like someone risk-averse has been replaced with someone risk loving, and neither looks like they're counting cards.
Do we have any way of knowing if that story told by Quirrell was true?
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:
