This may be a bit nit picky, but I think it would be an improvement if the principles in the document would be used in other principles examples.
For example, it is recommended that any property that has a mutable subclass (like NSString*), be declared with attributes nonatomic and copy. However, in most (if not all) of the other examples on the page, NSString is declared with nonatomic and strong.
