A social trust network implemented in combination with a networked communication platform which monitors information in messages communicated through a network, said social trust network comprising: a processor executing an application for conducting a search of a database to return identifications of one or more persons or groups of individuals and corresponding trust data and communication data; a trust network platform including an aggregate trust engine for computing a trust metric from said trust data, said trust metric being a quantitative metric of likelihood of a person or group of individuals providing information which is useful or of value to a user; an arrangement operatively associated with said networked communications platform for selective communication between said user and said one or more persons or groups of individuals using said communication data; monitoring means operatively associated with said networked communications platform, wherein said monitoring means are configured to parse a message of said selective communication, and extract information from the parsed message including at least one of tone of speech, speed of speech, and voice frequency variation expressed as quantitative metrics of a value or usefulness of said message to said user; and a user trust management subsystem for deriving additional trust data from said information of said selective communication monitored through said networked communication platform and storing said additional trust data in said database for inclusion in said computing of a trust metric corresponding to said person or group of individuals; wherein said message is from one of said one or more persons or groups of individuals and is responsive to an inquiry by said user, wherein said aggregate trust engine computes a plurality of trust metrics from said trust data, and wherein one of said plurality of trust metrics is a weighted sum of others of said trust metrics.
