Research by Global Pulse and other groups, for example, has found that analyzing Twitter messages can give an early warning of a spike in unemployment, price rises and disease. Such “digital smoke signals of distress,” Mr. [Robert] Kirkpatrick [who leads Global Pulse] said, usually come months before official statistics — and in many developing countries today, there are no reliable statistics.I shouldn't have been surprised by this; people who want to help people, just like people who want to make money, are innovative, hard working, and alert to new tools. I am pleased to learn of this movement.
