I can see why live view could be useful in certain circumstances when it would be difficult to use a viewfinder - so I would never object to it on some misguided principle.
However, my own "philosophy" of photography is that the camera is an extension of the eye and the heart. Somehow the link is more immediate and real when the camera is actually up to the eye, rather than being held at arms length. Seems to me that even a foot between the eye and the camera breaks a kind of mystical link.
So - I would probably use live view (if I had it) with some types of shots - but I suspect that, when I could, I would still use the viewfinder.
