Google uses a database of wireless internet access points to help provide you with all the fancy location/stalking services you enjoy on your devices. But now Google's got a (sort of lame and pain-in-the-butt) way for you to opt your network out of its servers.
All you've got to do is change your wireless network's name so that it has "_nomap" at the end of it. So if your Wi-Fi network is named "WINTER_IS_COMING" you'd just have to make it "WINTER_IS_COMING_nomap" It's not a big deal to do, really, but it's still kind of lame that Google forces you to alter something you wouldn't otherwise have to just to stay the hell off of its servers.
