Abstract:

Metaphor teaches. Metaphor influences. Are you drawing on its power? Perhaps not, because many major works on writing for interactive products make little mention of it. To help encourage better use of metaphor, this column describes both the usefulness of shallow metaphors and the potential of deep metaphors, while offering tips and examples.
