When you only have "an" idea it is not much. Once you start building it you find out that there is a whole continuum of things it could do, and then how to take advantage of the synergies you find. Once you build something then it is easier to build something else, but you don't really know that until you build that first thing. A single idea is not very valuable, the implementation is because it typically it has to consists of many ideas.
