Perhaps it's time to admit that arbitron is now a poor indicator of
readership entirely?  Many sites, and especially large, new sites have
gone to using NNTP feed machines and newsreaders on a variety of other
machines, both Unix and non_unix, to serve their populations.  This
lets them add news without heavily affecting the user distribution and
forcing everyone to have an account on a single Unix box where news
would be read/stored.  The old model of "everybody reads on a
(connected) Unix system" is quickly falling by the wayside, but
arbitron hasn't changed; even a group of Unix boxes connected via NFS
is difficult to grab arbitron figures for.  The problem of supplying
arbitron information when you don't even have access to, much less
administrative control over, systems that can read news via NNTP is a
real problem.  Until the protocol for NNTP offers some arbitron
features, don't expect an increase in the reporting percentages.

(n.b.  NNTP has it's own statistics gathering programs, but they
really don't show the number of users, just the number of connections,
which groups were read, how often, how many articles, etc.  In some
ways it's a more accurate gauge of demand than is arbitron.)

You are right that arbitron no longer measures what it used to measure, but
it does still measure something. I'm just not quite sure what that something
is.

When the NNTP spec was first circulated 6 years ago, I pointed out that this
protocol would make reader measurement impossible and asked them to change
it. They ignored this request, and the current NNTP spec makes it virtually
impossible to measure readership accurately. I guess they didn't share my
belief that readership was important.

Stan Barber and Brian Kantor tell me that the new NNTP spec will have in it a
protocol that will permit readership measurement. I would be delighted to
retire the 7-year-old arbitron technology in favor of this more modern
technique just as soon as it becomes workable.

About Spaf and the rules: it is definitely past time to apoint a new King of
USENET. It was past time 5 years ago, but not very many people noticed.
Spaf became King more or less because he announced that he was King. I think
that if enough people offer their fealty to a new USENET King, he or she
could be duly crowned.

I was aware of this.  That's why I tried to convince other boxes'
administrators to gather statistics for their box and have it
sent to a central account:
All systems that read news inside my domain should produce
arbitron statistics and forward the results to the central
account, once per month.  After a five day waiting period,
the results from the central account are gathered together
and the final computing step results in a Netreaders count
per newsgroup, which is identical to the arbitron input format.
So my domain hides several hosts, of which you'll see only one
arbitron report.
I know that not every host reports, but you'll get the idea.
