Labels are very important. I spend a lot of my time thinking about what things should be called and how they are labelled. Some people say I am obsessed. I believe that the naming of things is one of the most important things that Information Architects can do.
This is what can happen when you don't think carefully enough about names:
Team Blackshirt: Look for Team Blackshirt in the Gadget Gallery for the unofficial Windows Design Team gadgets. We’re checking those download counts every once in a while. Ah and the name? Well, of course we had to use a name that hinted at our design background. And actually I think some of us were wearing black shirts when we came up with it. (Microsoft)
Blackshirts : The Blackshirts were Fascist paramilitary groups in Italy during the period immediately following World War I and until the end of World War II. The term was later applied to a similar group serving the British Union of Fascists before the War. (Wikipedia)
