Iconography gets to the heart of what UX designers live and breathe: they can make or break the usability of an interface. It therefore stands to reason that their use is context–specific. Like every other area of user experience design, icons are best suited for the target audiences that will most profit from their use. It’s up to us as communicators, designers, and creators to identify those audiences and get the most out of our icons.
