Khoi Vinh is currently Principal Designer at Adobe, Design Chair at Wildcard and co-founder of Kidpost and previously co-founded Mixel and was the design director of The New York Times online. Khoi’s site, Subtraction.com, was one of the first blogs I started reading when I started designing over a decade ago and in this episode, I talk to him about how he started blogging, how writing has influenced his design career, and the the need for a more rigorous criticism around digital product design.
