Yes, I'd say it is. As my description says, part of the inspiration was classic fanzines, who often made use of collage and other creative uses of fair use material. With a "Do it yourself-attitude", I don't mean you can't rely on the work of other people, but rather that you should use whatever tool at your disposal to make something and not worry too much if it isn't slick and polished.
