Why are you so afraid? If you are so worried about 'big brother', then why are you on the internet? You are on the grid and they are watching you now. Look, behind you, here they come, run. As technology improves so does the means of everyone keeping track of everyone else. If you use a credit card you are being tracked, if you use a cell phone you are being tracked, if you use electricity you are being tracked, if you use the internet you are being tracked. This has been going on since the discovery of electricity in one way or another. The only way to get off the grid would be to move to a cave and never leave. There are so many ways we are being tracked already that we don't know about at least the RFID's we would know about. Fear is a debilitator, don't let it disable you.
