Sven, Martin - your perspective is valid of course, and defensible. But is that how we really think about expertise in other fields? If I asked you about the world's leading expert on brain surgery, would you break it down into component parts and suggest that we also determine/highlight the person who handles the anesthetics, and the journalist who wrote a history about the early days, and the briliant young intern who assists?

Peter:
Now you've defined what you're looking for. In your last post you didn't.
The answer would change if you were looking for the guy that knows the most about how the practice of brain surgery has evolved since the first hole was drilled in some poor guys head back in 1485, instead of the guy you're going to hire to get the clot out of your cerebellum in 2015.
Its still all about context.
