The “power of the crowd” is pretty cool relative to using data mining on large volumes of data to discern trends and to infer/derive new related data.
Google has the ability to present information on trends related to Google search terms. An interesting application of this capability is Google Flu Trends, which correlates search terms related to the flu and accurately predicts the incidence of flu in US states -
Does anyone know of other “power of the crowd” types of trend analysis tools/sites on the web?
