Novelty techno has a place as far as I'm concerned - not interested myself on the whole, but it can bring new people to more mainstream (!) techno I suppose. Like my housemate who DJs breaks and hiphop but somewhere heard and went and bought a load of random (and on the whole terrible - Buggles shranz?) techno remixes and from that has started taking more of an interest in and buying the odd bit of other (proper) techno.

Some 'novelty techno' definitely counts as a war crime though.
