Explain to me how "personalities" are relevant to a block chain. A potential delegate simply registers a public key. They don't have to prove their identity in any other way.
In order to register as a Delegate you will need to provide further information (e.g. full name, bitcointalk.org name, twitter, facebook, e-mail, etc.).
This enables voters to know who they are voting for.
Okay, this is missing from the handbook. It needs to be in there. I'm not completely convinced of the wisdom of this system yet, but I fully concede that tying the voting mechanism to real-world input adds a lot more legitimacy to this type of process.
