Perhaps the attached figure is of interest to others. I'm preparing a
talk about Octave and wanted yet another metric for the growth of the
use of Octave. Taking the number of posts per month to the five
(graphics/sources lists included) Octave mailing lists and the
octave-forge mailing list, and running a +/-1 month averaging filter
over the result, I ended up with the attached figure for my
presentation. Seems like we've been slacking off over the summer break :-)
