42. A computing device for selecting information to provide to users based on reputations of evaluators of the information, comprising: one or more processors; a content rater component configured to, when executed by at least one of the one or more processors: receive from a reviewer user a review related to an item available from a Web merchant; receive evaluations of the review from each of multiple evaluator users, each received evaluation including a quantitative assessment of contents of the review for each of one or more of multiple content rating dimensions available for use in assessing the review, each of the evaluator users having a single existing reputation weight for the Web merchant based at least in part on previous evaluations supplied by that evaluator user for multiple other reviews for items available from the Web merchant; and automatically generate at least one aggregate assessment of the content of the review based at least in part on combining quantitative assessments from the received evaluations for the review, one or more of the generated aggregate assessments being further based on the single existing reputation weights of the evaluator users in such a manner that a first quantitative assessment from a first evaluator user with a first reputation weight has a different impact on that generated aggregate assessment than that first quantitative assessment from a distinct second evaluator user with a distinct second reputation weight; an evaluator reputation assessor component configured to automatically update the single existing reputation weights for each of one or more of the evaluator users for the Web merchant based on a relationship of the quantitative assessments from the evaluation of that evaluator user to the quantitative assessments from the evaluations of other of the evaluator users; and a content manager system configured to, when executed by at least one of the one or more processors, determine whether to provide the review to another user based at least in part on one or more of the automatically generated aggregate assessments for the content of the review.
42. A computing device for selecting information to provide to users based on reputations of evaluators of the information, comprising: one or more processors; a content rater component configured to, when executed by at least one of the one or more processors: receive from a reviewer user a review related to an item available from a Web merchant; receive evaluations of the review from each of multiple evaluator users, each received evaluation including a quantitative assessment of contents of the review for each of one or more of multiple content rating dimensions available for use in assessing the review, each of the evaluator users having a single existing reputation weight for the Web merchant based at least in part on previous evaluations supplied by that evaluator user for multiple other reviews for items available from the Web merchant; and automatically generate at least one aggregate assessment of the content of the review based at least in part on combining quantitative assessments from the received evaluations for the review, one or more of the generated aggregate assessments being further based on the single existing reputation weights of the evaluator users in such a manner that a first quantitative assessment from a first evaluator user with a first reputation weight has a different impact on that generated aggregate assessment than that first quantitative assessment from a distinct second evaluator user with a distinct second reputation weight; an evaluator reputation assessor component configured to automatically update the single existing reputation weights for each of one or more of the evaluator users for the Web merchant based on a relationship of the quantitative assessments from the evaluation of that evaluator user to the quantitative assessments from the evaluations of other of the evaluator users; and a content manager system configured to, when executed by at least one of the one or more processors, determine whether to provide the review to another user based at least in part on one or more of the automatically generated aggregate assessments for the content of the review. 51. The computing device of claim 42 wherein the content rater component consists of means for receiving from a reviewer user a review related to an available item, for receiving evaluations of the review from each of multiple evaluator users, each received evaluation including a quantitative assessment of contents of the review for each of one or more of multiple content rating dimensions available for use in assessing the review, each of the evaluator users having an existing reputation weight based at least in part on previous evaluations, and for automatically generating at least one aggregate assessment of the content of the review based at least in part on combining quantitative assessments from the received evaluations for the review, at least one of the generated aggregate assessments being further based on the reputation weights of the evaluator users in such a manner that a first quantitative assessment from a first evaluator user with a first reputation weight has a different impact on that generated aggregate assessment than that first quantitative assessment from a distinct second evaluator user with a distinct second reputation weight, wherein the evaluator reputation assessor component consists of means for automatically updating the reputation weights for each of one or more of the evaluator users based on a relationship of the quantitative assessments from the evaluation of that evaluator user to the quantitative assessments from the evaluations of other of the evaluator users, and wherein the content manager system consists of means for determining whether to provide the review to another user based at least in part on one or more of the automatically generated aggregate assessments for the content of the review.
