This blog post is not constructive. The points are redundant summaries of what everyone already knows, ad-hominem attacks users of gpg based on a straw-man presumption, and does not educate the reader about how to construct better alternatives.<p>Attacking GPG is &quot;an easy target&quot;, and is really cliché - you get to sound profound without actually doing anything constructive. All of the arguments against GPG have analogous counterparts against using X509, yet there is no out-of-the-blue chiding of people who &quot;would voluntarily use&quot; X509.
