I'm not much of a designer. In fact, I'm awful at it. I am, however, interested in how it's done. I read and write plenty about customer success; along the way, (somehow) I found Samuel Hulick's site UserOnboard. His detailed descriptions of the user onboarding process in popular apps give designers an idea about how some of the most successful apps in the world keep you from quitting, becoming frustrated or getting no value. It leads by example.
