I've used it at work, but that was to satisfy a requirement for encrypting/signing software we distribute. I don't use it at home.
IMO there's a certain level of paranoia that is appropriate for personal use, and I have not yet crossed the line into believing that I need GPG in my personal life.
I do, however, tend to use encrypted tunnels to SOCKS proxies that I personally maintain if I web surf while on the road, if I'm doing anything more sensitive than looking up Google Maps directions to help me find the place I want to go to for dinner. So I suppose I'm more paranoid than your average smartphone or public WiFi user, but less paranoid than your average GPG user!
If the world isn't making sense to you, you're either drinking too much or not drinking enough.
