USDA hyped their "food compass" yesterday. I may be the only one, but the term "compass" led me to expect a visual metaphor, like the old food pyramid, but the metaphor is strictly verbal. The closest thing they have to graphics is an interactive map, which also has a pdf file to explain it.
I'd think they ought to be able to do better, more visual, more intuitive. (Of course, this is Monday morning quarterbacking by someone who has no suggestions to offer.)
