[comp.ai.digest] Characteristics of Discussion Lists

LAWS@IU.AI.SRI.COM (Ken Laws) (07/09/87)

              [Excerpt from a message to Steven Harnad.]


A problem with large, permanent lists is that they are primarily for
those on the fringes of a field who want to monitor or join what is
happening further in -- but not so far in that it becomes a full-time
occupation or involves incomprehensible jargon.  The professionals
already have channels of communication among themselves (including
personal visits, seminars, conferences, publications, and even e-mail
or phone calls) and have little time for list discussions that are
outside their own exceedingly narrow specialties.

As to the suggestion of continuing via e-mail, it's not really so bad.
Two options exist.  One is to cc everyone on each message, letting the
mailer propagate the cc list from one message to another.  It is usually
easy to add new members to such a discussion, but impossible to drop old
ones without retyping the whole list.  There is also a problem that BITNET
gateways don't add necessary routing information to message that are
handed over to the Arpanet.  The other option is for one person to
maintain a file with all the addresses, headed by a "label:" to suppress
the information in the cc field of each message.  All traffic is sent
to this one individual, who then remails it to the distribution.  That's
a moderated list.  (Anyone can get in this business!)

One of the charges in your Nay summary was that discussion of other
topics has been down since the fundamentals discussion took over.
I believe that's true, although there seems no rational reason for
it.  Even queries and replies have been reduced, although that could
be a coincidence due to the end of the school year and of the proposal
year.  A few people have dropped off the list because of the volume,
many more have added themselves because AIList was beginning to
border on their interests.  The effects are complex, and certainly
not just a linear addition of your text to whatever would have been
present anyway.

I believe that the proper model of a discussion list is the town
meeting.  AIList began with my own announcement of myself as
moderator, or chairman/speaker of the house.  A group of interested
individuals formed, and through custom and convention we have worked
out an informal social contract that governs the proceedings.  Part
of the contract is that participants pay reasonable attention to
the proceedings, if only to avoid redundant or naive remarks.  This,
together with the serial nature of current message streams, implies
that only one person (more or less ...) has the floor.  Part of
my job as moderator is to insure a balanced discussion, soliciting
(or forwarding) new topics and viewpoints.  Not every list is run
as a town meeting, but that's my view of AIList.

The symbol grounding discussion was carried out with great respect
for the participants and with incredible attention to detail.  AI
needs to grapple with the problems you raised.  (Whether AIList
needs to is debated in your vote summaries.)  The difficulty is simply
that people can't pay attention to everything, and your discussion
was demanding more attention than they could spare.  The other rings
of the circus require equal time.

Incidentally, much of the personal criticism has been sparked by the
one-against-all nature of your discussion.
If the level of discussion had been more approachable, we might have
had more people joining your cause and providing examples for your
position.  That would have been more interesting, and might have
reached an obvious conclusion or stalemate sooner.  It is a common
characteristic of net debates, however, that nothing is ever settled.
Points that are agreed to are simply dropped, with little or no mention
that agreement has been reached, and may even be picked up by some
other participant.  Net discussions generate a continuous stream of
ideas, but conclusions are lacking.  I thank you for repeatedly
reminding us that conclusions have not been reached in this particular
topic area, and hope you will continue to contribute to AIList.
