- "Hypertext substitution for Neil Larson"
- ========================================
-
- I spend most of my day on the phone, often providing the same information
- to many different people. That sounds like a great opportunity for
- hypertext. <FILE53 TALENTS>
-
- I could collect all my knowledge, advice, and solutions into a hypertext
- system, then let others give it out. But I won't do it for three reasons
- -- change, measurement, and enjoyment. For a moment, let's consider each.
-
- As for changes, I want to make whatever improvements I can to my software.
- While some people believe that I single-handledly created MaxThink, HOUDINI,
- and PC-Hypertext, most of the ideas contained in these products came from
- comments or suggestions from users.
-
- For that reason, while I may give out the same information to different
- people, I receive invaluable hints on future commands and uses for my
- software.
-
- As for measurement, in one sense I improvise software -- meaning that I'll
- put anything interesting in my software just to see if it may benefit
- users. I'll often ask the people that call me if they use some of these
- features or if a proposed enhancement would be important to them.
-
- In both cases, I'm trying to measure the potential capabilities of my software.
- That's how I do my market research . . . by talking to users.
-
- Finally, I enjoy talking to users who share my interests in thinking,
- planning, and writing. While my own academic training is in math and
- marketing, thoughtful users have introduced me to new ideas in medicine,
- philosophy, education, engineering, etc. That's nice -- as I believe I can
- always learn something from others.
-
- Now the twist!
-
- If I did not want to measure or change my world, then putting my knowledge
- into a hypertext decision-tree or into an expert system makes sense. But,
- that's why most expert systems are a disaster.
-
- If you build systems that provide advice, how will you know when the advice
- needs changing? It is only through the monitoring of the questions and the
- advice given that you discover whether your system is relevant.
-
- Simply stated, it is one thing to build an expert system (seldom done), and
- quite another thing to modify and revalidate the system (never done).
-
- What has this to do with hypertext?
-
- In an expert system, the stepping through of rules and linkages are
- automatic (and hidden) from the user. <FILE21 EXPERT> In a hypertext
- system, the stepping through rules and linkages is manual and always
- visible to and easily changed by the user.
-
- For these reasons, if you wish to codify a body of knowledge (i.e.,
- establish access patterns to particular segments), hypertext may be the
- better approach in terms of speed, visibility, and viability. However, at
- the core, using a hypertext system is:
-
- ┌────────────────────────────────────────────────────────────┐
- │ accepting someone else's thinking to ease your own. │
- └────────────────────────────────────────────────────────────┘
-
- While useful in most cases, hypertext is really only a representation of
- reality, and not reality itself. If reality is changing, your hypertext
- system needs constant attention to keep it closely matched to reality.
