I am not a huge fan of random big data projects for useless over caffeinated marketing ideals.
I do like projects like a certain Health Industry project started in 2006 that has become invaluable and very relevant with our current reforms.

I would dare to think that other industries, consumers, and regulators could find a use for similar collections of data and it's analysis. 😎
Anything worth doing is worth doing right since most things done wrong are worthless.
