dnf at 30%
I really wanted to read this book, but the writing is so bad, I don't want to force myself through this book.

The first 30% are an introduction to big data, and why the author thinks it's important. I didn't need to be convinced of this, I already believed that, so this felt more like an advertisement than something that was a good introduction. Maybe it would get better now, but the author doesn't use a precise language, overrates his data (which pretty much feels like pure speculation, because I didn't see any numbers) and makes really bad metaphors (I'm not interested in your grandma). So after having watched the google talks summary, I'm not gonna waste anymore time on this.
