How awesome is Google Analytics?

The other day someone mentioned how easy it was to know the geographic location of visitors to his website. The key is Google Analytics. I am sure there are lots of other analytics programs, but Google, with it's excellent track record with free, well-executed web tools makes me very happy. With their website, I just put a little piece of code into my webpages, and then viola, I can see where everyone is coming from to read my weblog. It is a huge trip, to see people from Germany or Brazil or Nebraska reading DCDork. I am sure it is great for people who want to make money from their website, but for me, it is all ego.
