I completely missed the whole things where apparently greenriders are "made" gay or something? (It's been a while, can't remember exactly.) But then, I first encountered Pern in fourth grade so the whole mating flight business made zero sense, which may have been just as well.

There was a Yuletide fic some years back that did revisionist Pern in a really delightful way--not everyone's cuppa, but it was very well done. I'm not really sure there's any way to revisionist Ship Who Sang, though.
