@ The Pacifist: Well said. Although as it says “OPTIONAL!” in huge letters on the sheet, people are able to put their own new categories on the sheet, and plenty of people put nothing but their name on their badges, which I think says it all.

Boxed or unboxed, the badges – to me at least – are less about what you actually stick on them than they are about being a conversation starter. They’re kind-of cool, like a roll-your-own-hanky-code.
