As noted in the post, Gatineau is built from Deepmetrix which Microsoft acquired last year, and they look to be aiming at a similar market as Google Analytics. Although Ian says they hope to not repeat the same problems Google Analytics did when it launched which was outages and slow response.
The functionality is not released at this point, but Marshall hopes that much of the MSN AdCenter tools and data are integrated as well, and even goes on to suggest that Google Analytics should snatch up Quantcast and integrate them.
Quantcast is definitely a cool service, and it seems to me like a useful acquisition for either an analytics company or even an advertising network or advertising technology company. Having that data on publishers integrated with an advertising solution would be rather handy.
Regardless, there’s no launch date on Gastineau, and from Ian’s post saying he hopes they get out in 2007 it could be a bit of a wait.
