As fandomcollision grows, its interests will as well, but for the time being, the listed interests reflect those of the creators/maintainers and their friends. As you join, if you so feel inclined, you can suggest interests to add to the list. Once the interests are full, we will begin to remove sub-categories (i.e. Slytherin, Hufflepuff, etc., as they all fall under Harry Potter) so that we can take full advantage of all 150 possible places.
