Interesting graph, my two observations are.... this doesn't include the first few years of air-l and any of air-meet and those would likely be revealing, but i don't think we have the data for those anymore, i might somewhere, but i might not. also, since the policy change on the reply-to, i've basically cut my reply's by what feels like 90%, so there should be a marked difference between the my work on he list from the earlier years and now, and also now i post from two different addresses. in fact, your graph might be an interesting tool to argue that air-l should go back to proper list settings instead of the current ones, but i've given up on that argument. -- jeremy hunsinger Center for Digital Discourse and Culture Virginia Tech www.tmttlt.com () ascii ribbon campaign - against html mail /\ - against microsoft attachments http://www.stswiki.org/ sts wiki http://transdisciplinarystudies.tmttlt.com/ Transdisciplinary Studies:the book series I am always doing that which I can not do, in order that I may learn how to do it. -Pablo Picasso
