Of course it depends on your targeted userbase, but that seems obviously
untrue for "most interested users". Humans understand secrets, and the
idea of an identity poem isn't impossible to comprehend. Casting things

strategy! Certainly most of my
nontechnical-but-concerned-about-security user encounters have indicated

their life rather than more.
