I don't sign in to Google Maps or other location-based services very often, and the accuracy of this report reflects that which is good to see.
I appreciate Google working to make this data public to the consumer so they know what they are providing and can turn on / off services as they see fit. If I had an Android device I would most likely be using Google Now a lot more and this data might be really useful.
Next, I'd like a listing of everyone that is being sold my data packaged anonymously, just so I can be aware.
