More MoR for money, on the other hand, would be following that glorious principle of exchanging money for goods or services.
As his author notes in the profile page mentioned, there's at least some people who argue that Eliezer went too far by even the mere offer of an altered schedule in exchange for donations -- right now I think their argument is extremely weak, however Eliezer would probably be treading actually murky waters if he had people give him money for the fanfiction itself (instead of the minor convenience of a quicker schedule).
Oh, right. Laws. They totally slipped my mind. Yeah, he should have gone with just accepting donations.
Update: Discussion has moved on to a new thread.
The hiatus is over with today's publication of chapter 73, and the previous thread is approaching the 500-comment threshold, so let's start a new Harry Potter and the Methods of Rationality discussion thread. This is the place to discuss Eliezer Yudkowsky's Harry Potter fanfic and anything related to it.
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. The fanfiction.net author page is the central location for information about updates and links to HPMOR-related goodies, and AdeleneDawner has kept an archive of Author's Notes.
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:
