Cliff notes for Web Analytics?  Well.. there's a new article on CRM News titled Analytics University: The Cliffs Notes that mentions the Aberdeen Group study that webmetricsguru.com is listed in:

"…The blogosphere is rich with Web analytics practitioners who take time from their day jobs to muse about all things analytics. Blogs are often a great source of information to learn about analytics topics, increase knowledge and expand resources. A sampling of prophetic blogs and bloggers includes: Lies, Damned Lies… (Ian Thomas), Occam's Razor (Avinash Kaushik), WebAnalytics.be Blog (Aurelie Pols), Web Analysis, Behavioral Targeting and Advertising (Anil Batra), Web Analytics & Affiliate Marketing blog (Dennis Mortensen), Web Analytics Demystified Weblogs (Eric T. Peterson and Judah Phillips) and Web Metrics Guru (Marshall Sponder). Each of these sites can provide hours of education and is likely to rock your notions of Web analytics while teaching you something you didn't know."

Overall, the CRM Buyer article is a "SparkNotes"on the Analytics University study but it does a good job of summerizing two fairly long PDF Documents - and it's worth reading if you want to find out more about Web Analytics.
