Google's at it again. Taking a service that typically cost (lots of) money, and makes it free for the world. How very nice of them. As they say:
Google Analytics gives us an opportunity to invest in our advertisers and everyone else who wants to create quality content on the web. Instead of spending money on web analytics, you can focus on creating targeted, ROI-driven marketing campaigns, and on improving your site design and content.
One day Google's strategy will become 100% clear -- and I really hope it is as nice as wanting to support "everyone else who wants to create quality content on the web."
