Stats from NZOSS online groups site

Thinking about transitioning from groups at http://groups.nzoss.org.nz/ to this forum, I gathered some data about the groups hosted there. Here it is for posterity (or the next time everything ends up in the bit-bucket)

What do these stats tell us, specifically about the state of F/LOSS in New Zealand and the NZOSS?
