I think the verification badge should do something else on top of just being shown. Some sort of a PKI trust system like with SSL certs that would point to a specific (possibly masked) email or web site that belongs to the person. In other words I want to know if this is Bill Evans the pianist, not Bill Evans the saxophonist or any other Bill Evans who is not even a musician or someone pretending to be one of them. Can social networks solve this? (I know, Bill Evans the pianist died a long time ago. Big fan of him)
