Re: I dont believe there is ever likely to be full privacy on the internet
"I dont believe there is ever likely to be full privacy on the internet"
That'd basically be oxymoronic. The internet exists to communicate data. "Full privacy" for everyone about everything would mean don't communicate any data... As you say, it's about agreeing boundaries. The system is still relatively immature (compared to walking down the street..), opinions vary, the scope is wide, and enforcement is difficult. We're a long way off.
You walk down your street with knowledge of the area / community, and having decided the risk is acceptable; there maybe some streets you don't walk down because you don't feel that's true.
The real difference vs the down the street analogy is the scale and extent at which it can happen. People elsewhere in the world can do it en-masse in your street, and every other street. That changes the discussion because you no longer know which streets are safe, or what communicty you're interacting with, so your ability to choose is being eroded. Oddly enough that's an inverse privacy problem, where those doing the monitoring have too much privacy.
