Reader feedback mechanism

There was a lot of negativity to Ravpapa's methods over at EN:WP (see here) but I for one applaud him for his intitiative and original thinking. As I say over there, we really do need "some official process whereby we can determine exactly who our readers are and solicit their opinions of the articles without them having to edit talkpages and us having to trawl those talk pages to collate the data. Some kind of WikiReaders forum perhaps?" It would seem that Ravpapa's basic idea is being considered favourably over here, which is great! Abuse? In what way? If people give their opinions then then they give their opinions, if they don't, they don't... can't see much to go wrong there except perhaps some incivility, oversimplification or overcomplexification etc, things we have to deal with anyway. Especially if a survey is permanently linked to all articles. How about a general forum, though?
