"You can do that with Django (and we’ll tell you how in Chapter 7), but one of Django’s core philosophies is that URLs should be beautiful. The URL /time/plus/3/ is far cleaner, simpler, more readable, easier to recite to somebody aloud and … just plain prettier than its query string counterpart. Pretty URLs are a characteristic of a quality Web application. Django’s URLconf system encourages pretty URLs by making it easier to use pretty URLs than not to." - Daniel J.
