If measured in "bytes of the gzipped mbox" it looks like there's a
*huge* increase of volume on Hackers in the past 3 months - well
over twice the historical levels; and maybe 4X 2002-2006.

Graphs of this metric can be seen here:

In some ways I think compressed mbox sizes are a more fair way
of measuring the bandwidth for these lists since it (correctly)
counts a large gzipped path as requiring more mental effort than
people top-posting brief messages on top of old threads.
