As to the second: correct me if I'm wrong, but the context seems to indicate that "the things [he] wasn't seeing" that his mentors failed to mention to him were A) mooning after Lily the way he did was "creepy" and B) still being in love with her years later was "pathetic," in Miss Felthorne's words. Going by canon motivations, Dumbledore would presumably not try to convince Snape of those things because his love for Lily, however childish and misguided, was the primary motivation for Snape's opposing Voldemort and protecting Harry.
What I don't understand, though, is why Voldemort wouldn't say anything. Breaking Snape's ties to Lily specifically and the Light in general was obviously to his benefit.
Also, as a side note, remember that MoR!Voldemort wrote the Evil Overlord List. Specifically, the idea that he was "not out to make his death eaters better at their jobs" contradicts Bahry One-Hand's internal description of two Death Eaters, which was
Two of You-Know-Who's own warrior-assassins, personally trained by their dark master.
Death Eaters are a big deal in MoR. And Snape bears the Dark Mark for a reason.
Also, as a side note, remember that MoR!Voldemort wrote the Evil Overlord List.
Except that instead of "I will not turn into a snake, it never helps," he instead wrote "Become an animagus"
Update: Discussion has moved on to a new thread.
The hiatus is over with today's publication of chapter 73, and the previous thread is approaching the 500-comment threshold, so let's start a new Harry Potter and the Methods of Rationality discussion thread. This is the place to discuss Eliezer Yudkowsky's Harry Potter fanfic and anything related to it.
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. The fanfiction.net author page is the central location for information about updates and links to HPMOR-related goodies, and AdeleneDawner has kept an archive of Author's Notes.
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:
