Exemplary methods and systems may help to provide content to a user and/or take to take actions on user's behalf, based on a context-specific user-network that includes surrogates for a user in a certain context. An exemplary method may involve: (a) determining a context associated with a first user-profile; (b) determining a context-specific user-network for the first user-profile in the determined context, wherein the context-specific user-network comprises one or more user-profiles that are surrogates for the first user-profile in the determined context; (c) using historical context-to-action data for one or more of the surrogate user-profiles as a basis for determining a context-based action that is appropriate in the determined context; and (d) causing a computing device associated with the first user-profile to initiate the context-based action.
