Thanks Patrick! As you suggest, specifically, regarding Avinash I had mailed him long back. He replied that VWO is very cool and I like how easy it is, but since I work for Google there may be a conflict of interest. Perfectly understandable.

Though there are lots of other bloggers in web analytics, SEO and online marketing industry. I have made a list (from Alltop and Technorati) and plan to start writing to them soon. Your strategy is interesting. I am using it already, pitching people using your and others' reviews.
