My city recently had one of those fluffy news segments on the shocking revelation that - get this - some sf/f fans are girls. Who talk to each other. If this is newsworthy, knowing about fandom demographics and K/S must be graduate-level knowledge. Hell, some people still have trouble with the concept of science fiction and are shocked to learn that, say, time travel is not a new story idea. It's a bit baffling. I mean, I do my best to ignore sports and sports fandom and don't understand the purpose of sitting on sticky metal bleachers waving a big foam finger*, but at least I know about it, and have some idea what terms like "penalty shot" and "foul ball" mean.

*Or whatever it is that other fandom does
