You are missing A LOT of buildings. This is just part of the main campus.
Don't blame me It's what Bing Maps shows if you type 'Microsoft Campus' , so go to the Bing building! HaHa
These are the building Paolo was talking about more to the north I guess...
It would be nice to kind of circle alle buildings and indicate witch person works where on what.. It would make a very nice deepzoom rich internet application! If i got the data I would not mind making the app.
