I personally have not had much to say because of my:
A. Being quite busy with my full time job (Permaculture Design
Consulting and Teaching)
B. It usually only respond to threads that are of specific interest to
me or if I'm doing some shameless self promotion
C. I do a lot of my Permaculture correspondance on the much busier
Permaculture Research Institute bulletin board
(http://forums.permaculture.org.au/) - because one is usually able to
take a thread along longer than I can on this one for some reason: again
that relates to my particular spheres of interest.
The Australian-based Permaculture Oceania list serve has just this last
week closed down and is apparently going to be revamped out of the
Permaculture International Limited web site. It too suffered from only a
moderate amount of traffic at times. Perhaps people respond better to
the bulletin board format or they are more comfortable with the
community there I don't know. There are a lot of very active people on
this 1600+ member PRI forum.
