well, kevin drum is here again. he's got a post about the half-blood prince that asks the very question i've been pondering since i read the book. it's very spoilery, obviously, but there's a good comment thread.

UPDATE: as pointed out in drum's comments, there's also a very good thread at alas, a blog, here. spoilers, warning, etc.

for those still interested, the zunta harry potter thread is here.

UPDATE II: this is a great theory about the blank that blank blanks. in the cave. heh.

UPDATE III: and another good theory about the blankity blank blank. dear lord. i need to stop.
