Between all the little rfid chips, gps, cell phone trangulation, credit and debit card tracking going on there is really no privacy left to us. The only real privacy remains in being so boring that nobody will pay attention to you. I blog, twitter, Facebook, post pictures and I don't generally worry about my privacy because I am in fact quite boring and don't have much to hide. (And no, I am not telling you what I actiually may have to hide - I have some privacy left.)
I hear that there is such a thing as rfid blocking. I wonder what the heck that does? Maybe people think they are being bugged?
I do think there is something to be said for THE IDEA of going off the grid, if not the reality. I would like to have some chickens, a cow, and a garden and be able to fend for myself. Well, except for the part where you have to get up early to milk the cow. Chickens maybe better - I don't think they are a lot of work if you have them out in the open. I do want air conditioning and internet though. Not much of an off the grid person am I?
