Yea. The approach to making an MLP rationalist fanfiction is not to change the original material, it's by working within the set format to provide rationalist lessons. If done properly probably indistinguishable from the canon episode scripts except for not being in a scrip format and being about slightly more advanced subject matter.
For example, from what I've herd about the minicamp:
"Dear princess Celestia, today I learned that although the idea that someponies opinion of you is infuenced by somehting as arbitary and wastefull as fashion might seem unpalatable, it can non the the less be unwise to ignore the fact that it is, even amoung friends. Ponies can not always control their subconius impresions, and this is no reason to in turn judle them.
I think you're both thinking a bit too narrowly about the topic of rationalist MLP fanfiction. It needn't be about correcting irrationalities of the original material (which I'm guessing was Vaniver's approach?) but it doesn't need to just follow the show's "how to treat your friends" moral lessons either... It could introduce new readers to some really advanced LessWrong concepts.
...ooph, I don't know if I should share the ideas I have on this or not. Because I am thinking of writing rationalist MLP fanfiction, and if so I'd prefer there'd be so...
(The HPMOR discussion thread after this one is here.)
The previous thread is over 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 latest chapter as of 09/09/2011 is Ch. 77.
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. 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.
