This document uses a metaphor of surfing to illustrate how people adopt new technology. It describes three types of surfers - short boarders who catch waves early, long boarders who enjoy waves longer, and skim boarders who wait for waves to finish. It analogizes these to early adopters, mainstream users, and late adopters of technology. The document also notes how wave conditions like terrain, currents, winds and underwater features affect the surfing experience, similar to how external factors influence technology adoption.
