It's actually the same tactic as the Weasley twins used to cover the "engaged to Ginever Weasley" story- plant so many make newspaper reports that everyone gets confused. And it kinda happens again after the Hermione/Draco incident. Guess Eliezer like the theme of people not being able to discern the truth from wild rumours if the truth's weird enough.
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 116.
There is 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.)
