This good is based on the popular but discontinued OKTrends blog, but now apparently active again becus of the book release. There is some more info in the book than can be found on the blog, but overall there is much more on the blog. The book is short (300 pp) and written in non-academic style with no statistical jargon. Read it if u think big data about humans is interesting. The author is generally negative about it, so if u are skeptical about it, u may like this book.
