BusinessWeak is the only liberal rag I subscribe to. The business coverage is good but the opinion pieces are a joke. The average income of a BusinessWeek reader is over $100,000. If any of their readers subscribed to the mushy headed thinking in the opinion columns (and I don't just mean the last page) then they wouldn't be making over $100,000 for very long.
I've heard Forbes is better but since I don't watch TV much and refuse to read the NY Times, I need to get some info from the other camp direct from the source at times.
