Goggling the Flu

NY Times today has an article about how Google is being used to track outbreaks of the flu. Turns out when people get sick they often Google to check their symptoms before making an appointment with their doctor. So where the flu is being Google'd the most can be reported to medical centers ahead of time, hoping to help control outbreaks of the flu. I think that is awesome! Technology is being used in a positive way to help people. It turns out that it also can predict where mortgage forclosures are rising. When people are getting in trouble with their mortgage they are turing to Google for help, googling forclosure. It makes me think what other trends could we predict with Google and how could we use them for good?
