I mentioned them (territories like Guam, Virgin Islands, etc.), although if they get included you might want to change the name of the thread to "American Empire" (or something less politically-charged-soundingish...)
Evil's map is pretty full, though, and to be honest I like that it at least commuinciates a better idea of the sheer size and diversity of the continental US in a way that other maps have not. The former USSR is also poorly represented as an extremely diverse nation in CC maps, ditto for China.
The "battle of languages" map of Flanders in the Final Forge is a great example of breaking nationlist stereotypes of homogenous people unified under one central government. In the case of the good old USA, how many people (native or foreign) are aware that there is no official language for this country? English is the most common, but it is not official (for decently good reasons that I won't go into).
Anyway, maybe I digressed a bit, but I mentioned it as sort of a brainstorm about different ways of thinking of the US, rather than in the traditional geographical sense. Evil D's map looks at the US with a focus on monuments, parks and sights... a unique "tourist" perspective that many people want to delete in favor of geography. There was an 'election' map in a different thread that tried to look at the US along crude political divisions.
Then there's cultural, historical, ethnic, economic perspectives... the list goes on. If people don't like the tourism gimmick, how about some other perspective that will communicate something new about the USA that the current CC maps don't have?
