Design Exercise: Labeling for Navigation

From any website of a large and complex organization or information space, such as a news site or a university website, choose an example of particularly good or bad labeling within the main menu system and justify your choice. Are the words chosen for the labels meaningful? Are they at the same level of abstraction? Are they distinct from one another? Is there a hierarchy, and if so is it coherent — can you predict and remember which labels are under which top-level category? How many of the labels are there at any one level? Can you tell where you are in the hierarchy when you are several levels down? Can you reach across the structure easily?  Does the navigation system also serve as a page title?
