Studies for the courts found in 1996 that even back then 60% kept the
default settings.  By now it's close to 100%.  I've tried paying people
to customize Xfce and KDE UIs.  It's just not in popular culture anymore
do to more than whine about defaults.

1) Rather than find out how many change it, find those who *do* change
it and find out how *they* change it and then study why.

2) Find out the frequency of usage of various functions (menu items).
Find out clusters of activity, that is functions that are used
frequently together.

3 Find out the relative importance of various functions, some may be
seldom used only once per document but be considered essential.

Then combine 2 and 3 to make your matrix, if you want primitive and
wrong answers.

4) Analyse 2 and 3 and do interviews to find out what is working
smoothly and where the problems are.

5) Have a taser charged and ready for anyone proposing to copy the
failure known as "the ribbon".  Ditto for vague, nebulous, or diplomatic
speech that could be interpreted as such.

6) Interview experienced trainers.  I can propose at least two.

7) Bring in real HCI specialists to do a) time-motion studies, including
eye-tracking.  Use as subjects educated people *who've never used a
computer before* to gather data.  Growing markets have lots.  Then bring
in novices and power users.  Compare and analyse.

etc.

I don't want to but, of necessity, have to.  Work out a scientific
approach, and the assessment can change.  In the mean time, #5 above is
probably the most valuable in the near term.

Of course.  However, survival of the fittest random changes doesn't
really work in a population of one program.
