Yup - Microsoft employee here but unaffiliated with that team. I love it, frankly. For large orgs that have thousands of SharePoint sites going back years(1), it's pretty fantastic. What would have been a dozen emails across two days to find some random doc explaining how to do something is now five to ten minutes of poking things into Bing.

1. TAM for this may be on the order of triple digits only for all I know, but if you work in a 50k+ knowledge worker org it's great.
