This is a reference to the webcomic/multimedia series Homestuck by Andrew Hussie, which features a species of timetravelling aliens known as the Trolls due to fact that the first ones that the protagonists meet were actual internet trolls. The Trolls have their own wierd system of romance built around four quadrants: the flushed quadrant (denoted with a ♥) which loosly aproximates what humans think of as romantic love; the pale quadrant (♦) which is sort of an intense platonic friendship wherein one partner serves as a stablizing force on the other, more unstable partner; the ashen quadrent (♣) whereby one partner attempts to mediate between to otherwise violently opposed partners; and the caliginous quadrant (♠), which can be described as "romantic hate", and involve such things as "hatesnogging" and "murderfondling". A more detailed description can be found here.
It should also be noted that this thread already contains at least on reference to a Hussie creation (cousin_it's "HP: Punch AM in snout to establish superiority"), so it's likely that fubarobfusco was primed to interpret things in that light.
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.
As a reminder, it’s often useful to start your comment by indicating which chapter you are commenting on.
