John Mauldin and Worth Wray are two really strong voices for the high yield debt problem. I have learned an incredible amount from them and trust them far more than Zero Hedge on such topics. ZH is the frontline pulse but if you don't want to have to filter out 85% of the crap, Mauldin and Wray are excellent sources.
So have John Mauldin, the New York Times's Dealbook, the Financial Times... There are better places to get your bear-market digest.
