Hi, there's quite an interesting think-piece here which raises a number of the issues we sometimes discuss: http://news.bbc.co.uk/1/hi/magazine/4260540.stm
I thought the quote from a Reuter's journalist was very well stated: "If a person standing next to you could see the same thing as what's shown in your image then you're OK." (unless you're standing next to David Blunkett, I suppose...) -- Regards, Bob
