I laughed at the part where Missy summons a rainstorm by Tempting Fate. (Although one of the laws of Tempting Fate is that you can never actually benefit by doing it.)
And she didn't even try "I am invincible!"
Well - she only wanted to prove a point about local physics, not make absolutely sure of her own destruction.
For the past two months, I've been writing, and posting, roughly two thousand words a day of "Myou've Gotta be Kidding Me", a story set in a "My Little Pony: Friendship is Magic" fanfic universe, "Chess Game of the Gods". Outside of the sheer NaNoWriMo-like exercise of pushing out near-daily chapters, I've also been trying to keep in mind the various principles I've learned from Yudkowsky and LessWrong, and to try to present them in a way that people who like reading MLP fanfics might be able to appreciate.
I've just come to something of a minor climax with chapter 60, and while I'll definitely be continuing the story, this seems like a good time to mention it here, for whatever feedback and constructive criticism anyone cares to offer.
