I saw an internal mail pimping this new service from the advertising wing of MS - Gatineau is:
Our new web analytics service, code-named Gatineau, is open for beta. In addition to all of the standard analytics features, Gatineau can correlate your web traffic data with our massive database of demographic information. This allows you to slice your logs based on gender, age and other characteristics of your visitors. The service is free.
Wonder if we can use it on our blogs?! :-)
Sign up for Gatineau beta here
