You're right. I apologise for the negative tone. PGP/GPG are some of the best tools we have right now for protecting privacy on a hostile network. Increasing and normalising its usage is vital to protecting privacy. I wanted to underscore the fact that the system is like a very strong lock - its level of protection depends very much on the surrounding weak links. PGP/GPG alone will keep you safe from a voyeur, but alone it will not keep you safe from an attacker. PGP/GPG does not, in my opinion, sufficiently make this distinction to the lay person. This is very dangerous because a false sense of safety is far worse for all parties involved. It is far too easy to go from 'this would be embarrassing if people knew' to 'they might kill me' information using the same keypair, because people think 'nobody can read this, it's encrypted'. That said, GPG/PGP is a great tool but in the end it's the skill with which you use that tool that determines how much it protects you and GPG/PGP makes it exceptionally easy to shoot yourself in the foot once you've learned how to use it in a basic way.
