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.
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:
You do not need to rot13 anything about HP:MoR or the original Harry Potter series unless you are posting insider information from Eliezer Yudkowsky which is not supposed to be publicly available (which includes public statements by Eliezer that have been retracted).
If there is evidence for X in MOR and/or canon then it’s fine to post about X without rot13, even if you also have heard privately from Eliezer that X is true. But you should not post that “Eliezer said X is true” unless you use rot13.
I think even simpler than this is the fact that the wizards don't have anything of worth to trade to the Muggles, since non-magical people have a hard time even seeing magical artifacts, much less using them.
Muggles have plenty of things that would be useful to Wizards, but the reverse isn't true.
Nothing of worth? The canon explanation for the Wizarding world's masquerade, from just a few chapters into the series, is that wizards would be in such demand by muggles that it would be too irritating and waste too much time.
Wizards have plenty to trade to Muggles - by providing services, not products.
* Magical cures to deadly diseases and accidents. A replicable cure can't be traded, but wizards can individually cure powerful and wealthy people. (Harry speculates that wizards would probably cure cancer in members of the Muggle government.)
* Military and covert operations, assassinations, coups, revolutions, etc. Apparate in, kill the enemy government and generals, win the war. Toppling any regime in the world that hasn't purchased magical protection of its own would give you a lot of money. In fact, every wizarding community should be able to demand arbitrary amounts of protection money from its local Muggles.
* Theft and spying (industrial and government).
* Subversion and interrogation of enemy leaders (by Legilimency, Veritaserum, Imperius.)
* Creation of single-action devices via Transmutation (like some of the things Harry tried in his experiments). Muggles can then study, analyze, experiment on, or copy the Transmuted devices while they last.
* Transportation. Launch satellites by Apparating into orbit! Rescue trapped people!
* A wizard could easily play a Muggle Superman - flying, being invincible, combatting crime...

Magical goods maybe, magical services certainly not. There are many things that magic could do to add value to non-magical objects, which then do not require any further magic to sustain (see Harry and Hermione's discussion about helping to manufacture nanotechnology and/or Alzheimer's cures).
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 97. The previous thread is at nearly 500 comments.
