It's useful for seeing exactly how to get somewhere, or finding alternate routes, but I have never liked having my property out there for everyone to see.
So far, Bing and Google (Maps and Earth) still have us as a vacant lot, and there is no street view on our road. Street view does go down the highway that connects to our road, but it still shows our road as nothing but a brand new dirt road with no one on it (so it's like... 8 years old at least!). Hopefully, we're enough in the boonies that it'll be a while before it's all updated.
When it is, they'll see a house and a shed, and... another shed with a coop on the end, a well, a propane tank, and a garden. Only the house and the shed that actually is a shed will be visible from the road, if they ever do street view down our road.
In the city, it was positively creepy how updated it all stayed! Made you want to get those camo tarps to put all over everything!
