In the passage you link to, I don't think Quirrell was interested in the prophecy as much as the plot that took Skeeter down. He seemed generally interested in the latter, and the demand for the paper was one of those "give me that's" where incredulity is pushed too far on something otherwise believed to be real.
As for objection #2, how would he have defeated the invincible Dumbledore, holder of the Elder wand?
In my preferred scenario, where Voldemort uploads into Harry as Harry seemingly defeats Voldemort, Voldemort doesn't have to defeat Dumbledore. Dumbledore becomes his ally, and likely passes the Order of Merlin onto him before he dies. If nothing else, Harrymort would have better opportunities to kill Dumbledore than Quirrellmort.
Ruling as Harrymort has more benefits and is more secure than ruling as Voldemort, even if we assume Voldemort would have won the war. Successfully terrorizing magical Britain isn't the same as winning the war. Once Dumbledore and the Order started using some terror of their own, I think it's likely that they would have eventually won.
The new thread, discussion 13, is here.
This is a new thread to discuss Eliezer Yudkowsky's Harry Potter and the Methods of Rationality and anything related to it. With three chapters recently the previous thread has very quickly reached 1000 comments. The latest chapter as of 25th March 2012 is Ch 80.
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: one, two, three, four, five, six, seven, eight, nine, ten, eleven.
As a reminder, it's often useful to start your comment by indicating which chapter you are commenting on.
