Protocols and delegation are only consequences of the true difference between Objective-C and the Java/C# mindset - which is that messages between objects are independent of the objects that send and receive them. In other words, messages are independent of the actual function call they cause in the end. So you can store, forward and broadcast messages, delay invocations, change invocation targets (classes, not just objects) on the fly etc. In yet more words, "late binding".
