I think the transformative aspect, the idea of writing things for us, has been growing and expanding and becoming more prevalent the more time we spend as a semi-cohesive community. Like, when you have a space like LJ or DW that houses a lot of people and where most discussions and interaction happens in public (unlike on mailing lists where a given list is only going to have a certain set audience), after a while the community becomes more and more aware of itself and starts developing more and more of a distinct culture. I mean that's a general internet feature, but in fandom I think this has truly led to some fascinating things.
