I really wasn't clear at all in that first post. I mean that articles and categories should belong to *many* categories, rather than being in a strict hierarchy. So in your example, put the author in all three categories - Fantasy writers, SF writers and Horror writers.
In the current system, articles can belong to many categories _and_ be in hierarchies. There already is http://en.wikipedia.org/wiki/Category:Science_fiction_writers , http://en.wikipedia.org/wiki/Category:Fantasy_writers and http://en.wikipedia.org/wiki/Category:Horror_writers , and each of these categories belongs to both the "writers" hierarchy (part of the "people" hierarchy) and their respective genre hierarchies as well.
I'm not sure what calling these things "sets" and "subsets" would add that isn't already there.
