Rule #4: Grow, Don't Build

Rule #4: Grow, Don't Build: "Since free software and other free culture products are formed by an organic, incrementalist process, they tend to be highly organic in their design as well. Free software is not so much built as it is grown. Thus, when considering a new project, you must think not about how to break it down into implementable chunks that can be assembled into a working product, but rather about how the project can organically grow—moving from working product to working product as it does so—becoming progressively more useful as it is developed."
