I never liked the idea of dividing electronic/dance music into genre/subgenre groups, although I understand the convenience of tagging it "house", "techno" etc., because the problem with such categorization is that a lot of people develop some kind of a one style cult and see the music, which falls outside the scope of their favorite style, as not worthy of listening to. I find it silly that a style should dictate someone's taste in music. Genre division is (or rather should be) for convenience only.
