The "rule of thirds" I have always understood as a simplification of the
Golden Mean which was known to the Classical Greeks. The GN is the
(recursive) ratio 1:1.618, and 3:5 is a reasonable approximation, as
provided by the vertical lines of the 1-10 focusing screen. 2:3 is a less
accurate approximation, but appropriate for the smaller vertical dimension
of the 24x36 frame.

Having John scribe your favorite screen would probably be very beneficial.
There are still times when a bubble level is useful ... although there might
not be any straight lines in the image your brain is amazing at telling
whether the picture is slanted.
But also changing the subject slightly, the link Larry posted to Gary
Bernstein near the end of January was very informative. One of the sections
(Lee Majors, Bob Soloman) talked about "the rule of thirds". Surprisingly
(to my uninformed self) it doesn't have anything to do with three equal
horizontal and three equal vertical sections. Thanks for the link Larry.
