Seeking your feeback on, well, feedback

Our user experience team recently proposed to a B2B client that we give users of their site the ability to provide feedback on individual content objects, e.g., a page, white paper, case study, etc. Based on the successes we've seen with consumers rating content, we were surprised to get quite a bit of pushback on this tactic in a B2B context. Have any experience with soliciting and acting on content feedback in a B2B setting? If so, it would be great to get your comments. Thanks in advance.
