Google Flu

This is cool. Google has launched a tool for tracking flu outbreaks, based on search query trends. Because the searches tend to be related to emerging symptoms, Google claims that it can locate flu hotspots up to two weeks faster than using existing techniques.

Unfortunately, it only works for the US at the moment. And one quibble: why don't the color schemes of the two graphs match?
