Because I read Yudkowsky being interviewed about writing HPMoR, and you should suffer too.
Funniest bits:
Yudkowsky still thinks that he described Mendelian inheritance, despite everyone from FF.net commenters on pointing out his mistake.
Wandering off into "the multiverse" and algorithmic information theory to fumble at explaining that magic works the way it does in a book because the writer made it that way.
This paragraph:
So to generalize that, let’s talk about the principle of “Make All the Characters Awesome.” This was an explicit process as I was envisioning the story, where I thought, for each character, how can I make this character awesome?
This comment:
My own belief about why so many people didn't want to believe Quirrell was Voldemort is that Eliezer is nearly incapable of writing characters that people actually dislike (perhaps due to, as mentioned: "make every character awesome," "give characters understandable flaws drawn from real life").
