13:50Dalton and Michael explain that a tarpit idea is unusually attractive, repeatedly attempted, and unsuccessful despite little changing in the circumstances that caused past failures.

Their advice is to study prior attempts, connect the problem to what current technology makes possible, and talk to users rather than relying on feedback or lists of ideas.
