Quite coherent article on the changing face of information and news flow in the investment world.  Twitter is becoming both an awareness tool and a “disintermediator” of access to preferred information sources.  Financial institutions that fail to recognize this are going to be left in the dust: “Simon Ricketts of the Guardian has noted that ‘Twitter does its best work in the first five minutes after a disaster, and its worst in the twelve hours after that.’” (@rolldiggity)
