Negative feedback loops

[Terry Sejnowski]

There is an inherent instability in the list that is caused
by time delays that can be over 3 days for some sites.  Negative
feedback loops with delays are well known to be prone to wild
oscillations.  A posting that elicits strong responses will
cause an impulse response that can last for a week because
remote sites are not aware that the posting has already been
through several cycles of responses from others.

Before you make an obvious reply to a posting, please look at
the date of the posting.  If it was posted three or more days
earlier the chances are that someone has already said what
you are about to say.
