Avinash Kaushik is a leading Web Analytics expert and practitioner. His first book has been highly anticipated and well received. You can go to the book’s web site at http://www.webanalyticshour.com/ , or read reviews and buy the book on Amazon at http://www.amazon.com/Web-Analytics-Hour-Avinash-Kaushik/dp/0470130652.
He is also the author of a famous Web Analytics bog called Occam’s Razor at http://www.kaushik.net/avinash. I plan on both getting the book, and subscribing to the blog.
