1. A computer-implemented method carried out by a computer processing system for user evaluation of at least one product that has a plurality of features whereby users operate user devices that are operably coupled to the computer processing system over network communication therebetween, the method comprising: interacting with a plurality of users via the network communication between the user devices and the computer processing system to assign user-supplied ratings to features of a particular product, wherein the features of the at least one product are logically organized into a hierarchical structure of feature levels, and wherein each user supplied rating corresponds to a respective feature level and represents a user derived assessment of at least one feature of the corresponding feature level of the at least one product; processing the user-supplied ratings at the computer processing system to associate moderation scores with the user-supplied ratings; interacting with a given user via network communication between a given user device and the computer processing system to specify a threshold moderation score that defines a first range of acceptable moderation scores; at the computer processing system, computing a composite rating for a given feature level of the at least one product based upon a set of the user-supplied ratings corresponding to the given feature level of the at least one product, wherein each user-supplied rating within the set is associated with a moderation score that falls within the first range of acceptable moderation scores, thereby omitting from the composite rating contributions of user-supplied ratings for the at least one product whose associated moderation scores fall outside the first range of acceptable moderation scores; and at the computer processing system, outputting the composite rating for supply to the given user via network communication between the computer processing system and the given user device; wherein the processing of the computer processing system selectively enables particular users to evaluate the user-supplied ratings and associated moderation scores with the user-supplied ratings whereby the particular users are selectively enabled based upon moderation points earned by the particular users, and wherein the moderation points are limited in number and distributed to a respective user by an automatic process that accounts for positive evaluation of the respective user's own user-supplied ratings.
