A Taxonomy of Ideas | Any idea you've ever had should fit somewhere in these four quadrants. The upper-right zone is the promised land, the intersection of "functional" and "well-structured" ideas where everything from "genius" to "interesting" lies. ("Boring" is also in there on the border, but mostly it's the good stuff.) The lower left (between "dysfunctional" and "poorly structured") is the idea graveyard!
