10. The computationally-implemented system of claim 1 , wherein said means for acquiring source identity data providing one or more identities of one or more sources that provide a basis, at least in part, for the inference data indicative of the inferred mental state of the authoring user comprises: means for acquiring source identity data providing one or more identities of one or more sensors used to sense one or more physical characteristics of the authoring user, the inference data indicative of the inferred mental state of the authoring user being based, at least in part, on the one or more physical characteristics of the authoring user sensed by the one or more sensors.
