1. A computer-implemented method for evaluating at least one product that has a plurality of features, the method comprising: interacting with a plurality of users to assign user-supplied ratings each corresponding to a particular feature of a particular product; associating moderation scores to the user-supplied ratings; interacting with a given user to specify a threshold moderation score that defines a first range of acceptable moderation scores; computing a composite rating for at least one product based upon a set of user-supplied ratings for 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 outputting the composite rating for communication to the given user.
