I've been using MeasureMap for a while to monitor blog traffic. Jeff Veen just mailed out to MeasureMap's alpha testers that it has been acquired by Google. It's blogged by Google here.
Ironically, Jeff's announcement states:
For the near term, you will see no difference in its operations.
Not quite true: it looks like the modding of the home page to add the Google link has messed up the layout horribly (linux/firefox)! Hopefully this acquisition will not see the problems that Google's acquisition of Urchin produced. At that time, Urchin became unusable and there were many complaints from existing users about price restructuring.
