When a good journalist looks at an artist and says "that's a good journalist," I think it's a good sign. Now, I haven't seen any of Mike Daisey's work myself, but... if I were him I'd feel pretty pleased.
UPDATE: Sorry, I wanted one more quote from Weigel:
It is not propaganda; you don't leave it pumping your fist and calling for the end of capitalism. You leave it with a better and more honest understanding of capitalism, one that has no comfortable place in politics.
