    I have to agree that this a weakness of the system. In effect, it asks
    people to learn algebra in order to do what they normally do, but do it
    better. Symbolic logic was intended as a step in that direction, but it
    failed to capture important nuances in useful ways. Our hope with
    computerized systems is that we can do a better job of making important
    relationships apparent to the beholder (or ourselves, when working on a
    hard problem) but it is not clear that we have the mental cycles to do
    that well, even as the beholder -- much less as the author.

    Fundamentally, we're looking for a good model of collaboratiove design
    and decision
    making, trying to make it function better using automation, with the
    goal of using it to capture the *next* great model. (We have two
    questions therefore. One, what is the best design/discussion model a
    priori, and second, what kind of model can we implement and make useful.
    Combining the two questions gives us: "What is the best model we can
    implement in reasonable time, and use to further our cause".

    Please follow up on that concept. It feels right, somehow. There was
    some discussion earlier on question-based mechanisms, and I note that my
    design work proceeds as a series of answers to questions, with the
    meta-question always being -- "what questions need to be resolved
    together, and which options answer the most questions", so I'm intrigued
    by this possibility.
