[Air-l] usenet demographics

I'm in the process of completing my thesis on the development of different social roles in usenet, and am trying to find some demographic statistics to shed some light on my qualitative findings. More specifically, I'm interested in knowing how many newsgroups are in existence (with worldwide distribution), how many distinct people participate in these groups, and what the gender balance is. If anyone knows of a source for such statistics and could point me to it, I would appreciate it. Scott ------------------------------------------------------------------- Scott A.
