A first step -- and a way to get over the "but nobody I communicate with signs/encrypts" chicken-and-egg problem -- is actually using the tools ourselves. In a larger sense, if we're going to talk seriously about adding surveillance resistance to the criteria for a "better Internet", the more of us use these tools, the more likely we are to make useful recommendations for usage and management of these technologies.

This is the reason I've started using GPG again ten years after the last use of my old key. I must say at least that GPGMail (on the Mac) has gotten _much_ better in the intervening decade.

Best regards,

Brian
