User blog:ZoshiX/Assistance for Subfandom

As far as I'm concerned, a fandom is any collection of people with common interest of a piece of either visual or literary fiction who either share interest or even create fan-works based on such. So under this definition, in all honesty, if you create something that a lot of people will like, anything can become a fandom, and anyone can start one. Also, is it possible to create an independant fandom for a work that is based on other fandoms, or is this just a crossover sub-fandom?
