This is a timely bit of information on web analytics. I plan to read and take notes and hopefully, learn something that has escaped me from the past several years. In 2000, I attended a web conference in Austin and talked with a man who was the seo guru for Yahoo! Through talking with him, I learned what to do, like use metatags; and what not to do, like use hidden text for keywords.
I have always used analytics packages, sometimes as many as three on each website, just to see what I can find out. I know the basics, my visitors, if they are unique or return visitors, who refers them to my site, in what part of the world they live, demographics, screen resolution, operating system, what pages they visited and how long they were on the site.

My favorite thing to do is to backtrack a person who leaves a really nasty comment on my site under an anonymous name and leave them a g-rated, but scathing reply on their blog about flaming and anonymity.
I take my thrills where I can find them. . . LOL
