btw to double check this, here's a better graph, of hits-per-2-hours over
that time period.

  http://taint.org/xfer/2005/dd_digits2.png

it's a bit clearer in that it uses proper axes, so you don't have to work
out the velocity of the curve to determine hit-rate; in this graph, higher
numbers = more hits in each time period, lower numbers = less. the
horizontal scale is the same as in dd_digits.png.

(graphed with

  gnuplot> plot "gpdata" with boxes
btw if anyone's curious.)
