I think it's clear that MoR is not (merely) parody, but a literary work in its own right that happens to be derived from an existing work by someone else.
Something that could be said with equal justice of _The Wind Done Gone_.
EY originally wrote the thing while (on record) attributing the characters and context to JKR, and then (on record) mentioned that JKR said she is fine with fan works and doesn't require attribution, after which he stopped.
I'm no lawyer, but I expect this means that EY is on record acknowledging his creative debt to JKR, and doing so because he thought he was legally obligated to. It seems like it would be hard to argue that MoR is fair use. This shows that the intent of the work was something the author thought was in range of her copyright, and thus not something like parody.
The new discussion thread (part 15) is 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 82. The previous thread passed 1000 comments as of the time of this writing, and so has long passed 500. Comment in the 13th thread until you read chapter 82.
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.
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:
