This has been a very good read. The subject of Big Data is treated quite exhaustively. What is currently a popular buzz-word is carefully disassembled and explained in proper-sized bits. There is some historical information about the field of statistics in there too, both interesting and, at times, amusing.
Big Data is here to stay, that much is certain. But while the rewards this paradigm can offer are great, we should also be aware of the risks to our privacy and the threat it carries regarding how it can and will affect our society.
