But - posts like these frequently jump to the top of hacker news, and there's clearly a feeling that access to new analyses and more data is going to change the world. I think this is probably right. I'd love to hear more discussion of how big data has already started this process.
Examples I can think of (and I'd love to hear more): - weather analysis for farmers (weatherbill / the climate corporation) - marketing (the target pregnancy example - http://www.nytimes.com/2012/02/19/magazine/shopping-habits.h...)
More examples?
