I like building pretty skeletons of a product first, which helps to dream up natural interfaces uninfluenced by the structure of a "backend". I've seen a lot of people conforming their frontend to some predetermined backend structure completely ruining the end user experience. Also found there to be a motivational aspect to this. Since I can't push the buttons or turn the knobs because its just UI at this point, I can't help but breathe life into it so that I can actually use it.
