As I read this post, I remembered having read that a number of people
have been working on power law theories describing generally the
distribution of links in a network, i.e. a rather uneven dsitribution,
with many nodes having small numbers of edges, and a very few having
very large numbers of edges connected to them. Thinking of Usenet
discussions as networks (nodes=actors, edges=messages), one would expect
the distribution of messages/authors to follow such a power law.
(Interestingly, physicists relate the occurence of power law-like
distributions to the phenomenon of self-organisation, confirming the
consideration by Karim.) Now, I was wondering whether anybody has
thought about analyzing the distributions of messages in newsgroups etc.
in such a way to find out about the type of distribution? Until now, I
only know of some Gini/Lorenz-curve analyses.
