But Grace, of course you're writing within a community. You're writing in a community of English speaking people; you're writing in a community of culturally literate people in the 21st century (I'm sure you make references to social/cultural things and expect your reader to pick it up?); you're writing within a community of FANS, i.e., if you write an SGA story, you must expect your readers to know th characters so you can shorthand, to recognize these characters, or otherwise you're just writing ATGs and not fanfic, right? And you're even, to a degree writing within the fantext community, even if it's only as a negative response, e.g., when you're writing a bad sex story, what you're doing is engaging with one of the fundamental tropes of the community...and inverting it. Clearly, someone who stumbles upon your story will have a certain sense of someone having lousy sex...but someone from the community within which (for which?) you're writing will understand the context in which the story is situated...
