I agree up to a point. There is a lot of value in curating expertise and bringing it together in one quality place.

That said, for kicks I looked through The Economist's media directory and it is indeed pretty London-centric. While I have no doubt that its correspondents are quite knowledgable about their beats (and I assume have plenty of good contacts), it's not like The Economist has a lot of big foreign bureaus.
