The Neiman Journalism Lab ponders the question:. :
Why has Rich embraced linking when his peers have not? "CThe theory was: Why not be as transparent as possible by showing sources, when we could?%u201D he told me recently.
and
Rich says his linking is as much about backing up his argument as it is about adding background. If one’s argument is only as good as one’s facts, Rich sends you to his facts. “Now, sometimes it’s unlinkable material,” he says. “But why not give the reader, if he or she wants to, the opportunity to see the sources, or a source, when it’s available? It helps bulletproof the column, because if they say ‘He must be making that up,’ they can look and see — here’s the source, take a look and judge it for yourself….If I’m citing a figure, at the most banal level, from the Labor Department or a poll or an economic report, [why not] link to the whole document it comes from?”
