Because we know that users try to understand URLs, we have an obligation to make them understandable. In particular, all directory names should be human-readable and should be either words or compound words that explain the meaning of the site structure. Also, your site structure should support URL- butchering where users hack off trailing parts of a URL in the hope of getting to an overview page at a higher place in the site hierarchy. Of course, it is better if users can navigate your site structure using your navigation buttons, but we know that a lot of users use URL-butchering as a shortcut: Such users should get reasonable results (typically a table-of-contents-like page listing the information available at the desired level of the hierarchy).
