interaction design. I agree this is super important. I also still think the founders should be doing it. One could argue that for many products, traction starts with interaction design. Good interaction design involves finding out how your user thinks about a problem and then finding a solution that naturally fits inside the user's mental model. Wireframes, etc, all flow from that core revelation. To do this, sometimes you need to interview (potential) customers, study their habits, and really understand their needs. So it should go without saying that founders should be doing interaction design, but this is first time I've ever seen it put plainly. The opposite situation, where founders don't have a deep sense of their users' needs and habits, is a recipe for failure.
