Collaboration on line starts to make sense

Ross's Power Law of Participation is brilliant, because it explains how valuable metadata can be fed into any collaboration tool. It can be combined with Janet Salmons Collaborative Taxonomy of e-Learning , which is more on the right-hand side of Ross's curve, and goes into more detail about how collaboration activities take place. By the way, "collaborate" looks a little awkward in the list, because it's the only action that you cannot take alone and thus does not only depend on you. But maybe what Ross meant is "contribute".
