The fact the entire model is based on articles in a printed journal. I really like the Cochrane Collaboration systematic reviews. As part of the article interested authorities can ask pertinent questions and receive responses. The best we get in most journals is "cited by" links but that's it. Is it being cited because a point is contested. If so, what point is contested. Does the citing paper make a good case. It it being cited as an inspiration for some derivative research with new applications in a different context; if so does that reinforce the methodology in the paper you are looking at. Why not have something that quickly helps you determine whether the paper has been reproduced, and maybe even uprate it if so. And so on.
