The "unscribed plate" or "blank slate" ... in this case ... not knowing anything about a person, outside of the hobby. For example, do I want to know that a provider is talking about having children with her SO? Do I want to know that a provider has an SO, at all?
I'm thinking, just me, that I'm really not interested in knowing someone's real name or about their lives. In some cases, I do know .. and it's not a big deal. But generally, I think I would rather just deal with hobby side of things. Just sayin'.
