No hate for people who are deliberately keeping cheap immortality from the world's population?
You are making assumptions about what how much immortality the Philosopher's Stone allows. For all you know it may allow e.g. a maximum of 7 people immortality, be only creatable once per five hundred years, and/or require the heart of an adult dragon per each person given immortality.
Revealing the presence of such a device (not cheap immortality, but rare immortality) might well cause more loss of life in the pursuit of its possession than it would cause otherwise.
Ofcourse Harry would still be furious at Dumbledore for not analyzing the stone in any way he can in attempts to find a way to mass-produce it or atleast its effects.
Least convenient world apples, but I'd bet Dumbledore and Flamel haven't been looking for cheaper ways to create more Stones, because it just isn't their goal. (And they're already in trouble because they have to guard the one stone from Voldemort.) If Harry knew, well, I'd bet his eyes would be ice and his voice would be distant darkness and... er, I mean, he'd go Librarian-poo crazy.
(The HPMOR discussion thread after this one is here.)
This is a new thread to discuss Eliezer Yudkowsky's Harry Potter and the Methods of Rationality and anything related to it. There haven't been any chapters recently, but it looks like there are a bunch in the pipeline and the old thread is nearing 700 comments. The latest chapter as of 7th March 2012 is Ch. 77.
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.
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.
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:
