This is kind of neat. Google is using search data to chart
Flu trends in the United States! They say they have found that the volume of searches for particular keywords are a great indicator for how much Flu activity there is in certain regions. Here is a quote from their site "We've found that certain search terms are good indicators of flu activity. Google Flu Trends uses aggregated Google search data to estimate flu activity in your state up to two weeks faster than traditional systems". Gnarly!
