Since programmers and other tech workers still have difficulty understanding the details of Persona, this seems to be a clear PR issue. It's a lot like trying to convert normal people to Linux by telling them it's great and if they don't believe you they can read the source of the kernel. Not a very compelling defense.
From there, you can dig as deep as you'd like--we have docs to help with building an identity provider, integrating Persona into an existing site, even a list of pre-written open source plugins in a ton of languages/frameworks.
If none of that works, drop by #identity on mozilla IRC and tell us our docs suck, so we can prioritize making them better.
