My only "privacy" defense is to not do or say anything online that I consider really personal and really would hate the world to know. Which is not that much actually. So what if people can google me and find out my name, job and where I live and see some pictures?
Lucky for me, I went through all the really embarrassing stuff some time before I or any of my friends ever even used the internet or a digital camera
Oh damn, now I feel OLD!
