Guess what! Since I moved to Germany (from the Netherlands), I noticed that people send a lot of encrypted mail. Not random Germans, sure, but where in the Netherlands the security and broader hacker community was hard to convince, in Germany it's quite widespread. My colleagues (security firm) and friendly security firms (when we collaborate) expect nothing less, and even customers supporting it is not rare (it was very rare (like, one customer in dozens) when I worked in NL).
It depends on your peers whether you find PGP is usable or not, it seems.
Then again, in Germany quite a few websites used OpenStreetMap before it was cool^W^W google raised their prices, and Linux is also more widespread. I wonder what it's caused by and how we can encourage it, since I think we (HN) would generally consider those things to be good, at least for fellow hackers, even if the tech has some edges too rough for the general population.
