As I recall, sending variables of type id<YourProtocol> useful messages like retain and release generate a compiler warning, whereas NSObject<YourProtocol> are fine.

I could be wrong on this, but I definitely recall thinking it was a stupid compiler behavior.

However, being totally anal, if you are going to document to the caller all the protocols that you require an object to respect, you should do it properly.  Which probably means using id<NSObject,YourProtocol> - if you put it in a dictionary, you need <NSCopying>, etc.
