Google Analytics

I recently heard about and signed up at Google Analytics. This is a cool site that tracks all kinds of information about visits to your web site. I can see not only how many visits per day this blog receives, but from which countries, the average length of visit, the types of internet connections and web browsers that are being used by those viewing this blog, and many other interesting facts. Although, it doesn't tell me what color shirt most people are wearing when they view my blog, or if they yell obsenities at the screen.
