The current structure of this forum is a very good example of the problem of not linking responses to given postings. I have come into the discussion quite late and therefore all of my contributions are at the end of the thread although some of my comments refer to postings quite early in the thread.
The longer this thread becomes, the more problematical this will become. Matthias can do a wonderful visualization of our own UAB forum structure that will be just as destructive to rational discussion as the present .lrn forum.
