+2. Adding __str__() to models
+
+Although it's not a strict requirement, each model should have a ``__str__()``
+method to return a "human-readable" representation of the object. Do this not
+only for your own sanity when dealing with the interactive prompt, but also
+because objects' representations are used throughout Django's
+automatically-generated admin.
