Consultation or Comment Request via an Open Feed

So I think it would be cool if there was a way to make a feed that would be in someone's reader or something that was just there so other people could post things they wanted comments about by the reader. I think this would be good for people who were often doing consultation or who's opinion was often requested on certain things. I have set up some personal shared lists in my Google Reader that go to specific people, so whenever I get an item I want to hear from them about I just tag it accordingly. I think this is interesting and useful but even cooler would be like a feed address that people could mail to just to get questions answered by someone offering this service. I guess that could be set up pretty easily. Perhaps I will do it after lunch.
