Loll, comment discrepancy XD. The thing we'll never figure out. I suppose it also has to do with the kind of slash. While Sam/Dean has the forbidden love kinda thing going for it, it's pretty much spun away from regular show-world SPN fic to mostly AUs. RPF has its own set of complicated relationships and taboos that writers seem to like writing about and then there's just utter cute fluff and AU world building. And there are readers for all of these things (or kinks?), perhaps MORE of them compared to regular show-based fic? (Incidentally on AO3, my RPF and Sam/Dean dark-fic has more hits and kudos than other things, LOOOOL. I don't understand this phenomenon)

I think we're gonna end up with a thesis on this stuff. XD
