The secret is out: Microsoft is developing an analytics tool for Adcenter that will compete directly with Google Analytics. The information was leaked a few days ago by Dave Naylor, who learned of the analytics tool (codenamed “Gatineau”) at a Microsoft briefing in London. Somehow he got a hold of some screen shots and published them on his blog. This prompted a blog response from Ian Thomas, a Microsoft rep involved in Gatineau’s development and transition to the market. According to Thomas, Microsoft was about to make a public announcement about the tool when the leak occurred.
