Google is known for weird projects that make sense. Here is a great project – Flutrends. This tool give instantaneous measurement of the flu epidemics level based… on the number of searches related to ‘flu’ on Google! This turns out to be quite an efficient way of crowdsourcing the information.

(more info and more countries covered on Google Flutrends – the same tool also covers Dengue)
What are the troves of data that are available but not exploited by those companies like Google (or at least, not given out to the public?)
As usual I am aghast at the power of the Fourth Revolution. Do you know other similar examples? Please comment!
