There is so much data that is being generated and collected and not used for anything at all, data right now can safely be called exhaust fume. Some is being used, but most is not.

Just being able to map all that is being collected, let alone making sense of it, is an industry in itself.

Being able to map and then make intelligent use of -- now that is a big one. And hence the term Big Data.

Big Data use that does not compromise privacy will go a long way. Think of it as excellent customer service. Half the time they don't even ask what you want, they already know.
