Cocoa is full of singletons. Is there a logical/conventional difference between when the Cocoa APIs use

NSSingletonObject *so = [NSSingletonObject defaultSingleton];

versus

NSSingletonObject *so = [NSSingletonObject sharedSingleton];

?

Not a huge thing, but I don't really see why sometimes one is used versus the other.
