lmao. I actually read fanfic before ever reading the books. Of even seeing the movies. lol I never would have given in and read the books if it weren't for fanfic. ^_^
It seems like the other stuff tends to follow fandom. We all invade with our slashy goodness, and then we make ourselves right at home with our other fandoms and knitting and cooking and ranting about everything and anything we can... The other things will follow us soon enough.
