Today, I have the honor of interviewing Avinash Kaushik, author of the bible known as Web Analytics 2.0, and a digital marketing evangelist at Google. He also has a must-read blog called Occam's Razor. Occam's Razor is a principle championed by statisticians that can be summarized as "as simple as possible but not too simple". It is a principle and therefore it also draws controversy from some quarters. Kaushik's blog is a place where you can pick up Numbersense. He writes about Web data, which is a huge part of Big Data.
