Joel and Kristin talk through their feelings about intuition versus analytics, user testing and other metrics when designing and writing. We discuss how agile methodology has changed our approach to work, both in terms of development as well as writing and other business endeavors. We debate value of AB testing and how it can be jeopardized by confirmation bias, as well as how testing can destroy authorship and the wholeness of a design. How can you really measure delight and brand engagement? Which metrics are useful and which are not? Kristin also invents Delight Spray®, coming soon to a store near you.
