I agree. Please do what Peter suggested, but please don't include this
message into your analysis ;-).

Not sure where is my own archive from 2000 forward, but since I
switched to Gmail at the end of 2004, I quickly grabbed conversation
counts per year:
2005 7,831
2006 7,381
2007 6,247
2008 5,009
2009 5,249
2010 5,295
2011 4,841
here is the individual message count obtained by summing monthly
totals on pdml.net, or alternately by counts of mail-archive.com
searches within 6 months of 2 July of given years (this search
captures a year give or take a day):
year pdml mail-archive
2006 68271
2007 60383 60201
2008 45822 44367
2009 52887 54505
2010 52122 53697
2011 41848 46731
i double-checked the 2011 figures and cannot explain the large
discrepancy; the average length of threads (consistently just under 10
based on conversation count) could be considered a measure of mailing
list health — 10 is good
just for fun, here is monthly message volume from pdml.net charted to
show seasonal and yearly variation (2006 and 2012 are partial);
