What's interesting to me is actually something that stems from her post, which cautions fanfic writers to keep in mind the difference between fantasy and reality. When I entered SPN fandom, I was wary of incest fic, and then when I did start reading it, I couldn't read fluff or schmoop or established relationship or anything but angst, really. And since I'm not a huge fan of the angst genre, I did slowly branch out (within the Sam/Dean pairing). And now all it takes is a little suspension of disbelief and a well-written story and I'll read most anything. So when I go back and look at my reading material with an observer's eye, it might seem...off. And while that wasn't what heatherly was warning against directly, it seems like part of it.
