Kindergarten Teacher Makes $700K Selling Her Lesson Plans To Other Teachers

This story combines just about everything I find interesting about web entrepreneurship: bootstrapping; easy, quick wealth; the economics of uncovering existing value; and the economics of replacing expensive "authorities" (e.g. textbook companies) with superior products sold peer-to-peer (e.g. this teacher's lesson plans). The only thing it's missing is lasers and synthesizers.
