The more things stay the same, the more they change, but how does that make this irrelevant? "How long is a string?" isn't necessarily irrelevant; it's just nebulous. This might just be another example of The Thread Which Must Not Be Named, but the relevancy seems to depend on individual interests. In other words, it might not be relevant to you, but can still be perfectly relevant to others...can't it?
No, it really can't. To be relevant, by definition, it must relate to something, and the "something" hasn't been defined. That's what's wrong with this whole nonsense thread. If you fail to define your terms, it isn't a conversation, it's the Tower of Babel.
