The computationally-implemented system of claim 15 , wherein said means for determining a second inference data indicative of an inferred mental state of the second authoring user during or proximate to an action executed in connection with the particular item and performed, at least in part, by the second authoring user based on one or more physical characteristics of the second authoring user comprises: means for observing the one or more physical characteristics of the second authoring user during or proximate to the action executed in connection with the particular item and performed, at least in part, by the second authoring user.
