Just read on Slashdot:
Details of Microsoft's answer to Google's Analytics have leaked online. Screenshots have been posted on the Net of the new "Gatineau" Web analytics tool that Microsoft now says will be available in beta this summer. In a blog post, Microsoft's Ian Thomas also reveals that Microsoft will use Live ID (formerly Microsoft Passport) profiles to get its demographic data."
Funny how the Slashdot poster noted this as coming from the "still-wouldn't-base-any-important-decisions-on-it" dept.
