What kind and level of privacy do we want or need?
There is the privacy that says, "I don't want everyone in the neighbourhood knowing my lifestyle".
Or there's, "I want to protect myself from identity theft"/ "Don't want the burglars to know I'm on holiday".
Then there's, "I'll be damned if I'm going to help these companies bombard me with adverts".
Beyond that there's "I don't want anyone to know anything about me, not now not ever, not in this life or the next".
Beyond that there's paranoia.
And finally there's commentards on El Reg.
