I'm thinking of general fic improvement things. As in really considering whether this or that exclamation is OOC, whether there are too many Americanisms involved in a Britfic and vice versa, whether a "steamy crotch" might seem painful etc... what I consider old skool fic is the majority of fic published in early to mid-90's zines, lightly edited or not edited at all. I think that the Internet has been a major force in promoting the goodness that is beta reading, getting writers to really think of the details in their stories, that sort of thing... I don't think there's a cure for the ubermush, though.
