Everyone online now knows where you live!
...if you use WiFi.
Are you using WiFi right now?
At your place of residence, do you have WiFi enabled?
If you answered yes to either of these, congratulations! We all have a 99.99% chance of knowing your exact GPS coords!
Get Opera 10.60, and go to: http://www.opera.com/portal/geo/ or http://html5demos.com/geo
It also works on Firefox, though it is designed for Opera.
Anyways, yeah..... it's some company named Skyhook that partnered with Google. You know, Google Street-view.. how they go by in those cars and take pictures of your house from the road? Yeah, those people. Anyways, Skyhook has been doing this shit for YEARS. They don't just do it once, they do it again and again. I moved a few months ago and they already updated my router SSID's corresponding location.
So yeah, long before streetview you have this company called Skyhook that sends cars with GPSes and WiFi sniffers. All they do is map the location of ESSIDs/MAC addresses. Then they sell this to device makers and software companies so that they can have some kind of "WiFi GPS". (Skyhook, more like Skynet, amirite)
I am really tired right now, but I just wanted to throw that out there.
Thank all deities that we live in a country where if major companies log all your information (even private sometimes), they can get away with it!
Call me a tin-foil-hat all you want, I am sure NO ONE wants this information logged about themselves.
