Now Mad-Eye Moody was turning slowly, always turning, surveying the graveyard of Little Hangleton. [...]
Moody didn't actually need to turn to survey the graveyard.
The Eye of Vance saw the full globe of the world in every direction around him, no matter where it was pointing.
But there was no particular reason to let a former Death Eater like Severus Snape know that.
Some time later:
"You see in all directions," Harry Potter said, that strange fierce light still in his gaze. "No matter where that eye is pointing, it sees everything around you."
Oops.
Just because he has no reason to tell Snape doesn't mean he has any particular reason to fear the knowledge getting out. He's already earned his spot on the Supremely Dangerous Wizards list.
Kinda makes me wonder why he didn't conceal the fact that he has a magical eye at all, though.
Edit: New thread posted here.
This is a new thread to discuss Eliezer Yudkowsky’s Harry Potter and the Methods of Rationality and anything related to it. This thread is intended for discussing chapter 86. The previous thread has long passed 500 comments.
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: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16.
