Mish Shedlock is an economist who was blogging about the US bubbles and troubles a long time before they burst.  He was seen as "permabear", "buzzkill", "unrealistic" in 2006.  Remember Peter Schiff's warnings?  Met with the same defensive posture -- they laughed in Schiff's face at the very peak of the housing bubble in the US.  FWIW, Shedlock has turned his attention to Canada.  His articles on Canada (and there are lots of them now) aren't written from opinions or bearish feelings.  He uses data and facts.  Having Shedlock issue warnings on your country is about as dire as Meredith Whitney critiquing a bank.
