It does seem to me as if there are too many threads. I am finding the discussions fascinating but since it is a busy week, with limited time I can only sample in what seems a too-random fashion. In spite of your valiant efforts to act as the matrix of all this poetic ferment, it may be just too daunting for one person! Maybe it would be best if you set up 3 or 5 more general thread topics at the beginning, and posters weren't allowed to start new threads. That's a method I have used successfully for online teaching.
