I'd love to read that post! Also, agreed about graphic horror. I find that things like torture scenes also hit me so much harder. There's a scene from... I think it's FayJay's recording of "Gypsies, Tramps, and Thieves" that would never have been as horrific on the page. Juice has also done one that made me put done my MP3 player and go do other things for a while, because I couldn't shake the terror and horror of it.

And whether podfic readers have stories that they'd love to hear read, but can't do themselves
I don't think that it stops people as much in podfic fandom, but I find that some readers are better suited to some genres than others. I'm trying to suggest that stories outside of those genres are badly read, but that a reader might have a more intuitive knack for drama than crack, or vice versa, and that that gives those stories are extra sparkle (or some other glittery metaphor!)
