While I have a personal dislike of Krugman's writing style, I think the Times needs people of his calibre on staff. Ideally he would have handed the torch over some time ago (the long arm of boomerism) but at this stage it seems that the Times, and most similar organisations are going the way of daytime television: Focusing entirely on a naturally eroding generation until one day they just vanish.
Journalism is too important a task to go down with them though. I wonder if the Hindenburg research model could be a way to fund it?
