Most definitely.  And a graph-based data model should be general enough to
enable fine-grained addressability of those types of documents.  Probably
something I should make more explicit in my paper.    (03)

I use the term "graph" in its mathematical context, not in the context of
graphics.  Hence, "graph-based" instead of "graphical."    (05)

Good question.  See:    (07)

Both are interesting points.  Do you have some proposed solutions?    (010)

My suspicion is that the solutions to these problems would fall outside
the scope of the OHS itself.  That's not to say that these problems fall
outside the scope of Doug's mission.  Remember, the OHS is only a small
(but important) part of a tool system, which itself is only a small part
of an augmented human-tool system universe.  It's important to think about
the entire universe -- that is what Doug's philosophy is all about.  And
if the solutions to the problems you present above are not the OHS's
direct responsibility, the OHS developers must still be aware of those
problems, so they do not inadvertently deaugment those solutions.    (011)

Don't worry, Henry; I'm a believer.  I've taught math to a lot of kids,
and have worked with a lot of non-technical people on technical issues.
I've learned too much from people of all demographics to believe that I
can ignore people on the basis of their job description, training, college
degree, or age.  And I've had too many patient mentors over the years to
believe that I can just ignore people who aren't as knowledgable about
certain areas, but who want to learn.    (013)
