So far, it's looking pretty much the same for me. I like Supernatural but I'm not running out to read fic the way I did with SGA. (And thanks for the compliment! *blush*)

At least some of it, for me, is that canon changes so fast in SPN -- as the characters' relationships evolve, fic would quickly become AU. And then, too, canon is just supplying most of what we look for in fic. I've discussed this with xparrot in the past ... that there's hardly any incentive to read or write fic in a fandom where canon supplies most of the character development, angst and h/c that would normally need to be supplied by fic.
