And if I'm going to read a list, I'd
much rather it be well run than just easy to post to. I define well
run as _both_ spam-free and lacking in moderation delays.
I define "well run" as having a high signal-to-noise ratio,
low moderation delay, a well-defined moderation policy that
evaluates messages visibly and impartially without considering
who authored them, and a low barrier to successful posting
of relevant content - even by non-subscribers.
Expecting contributors to explicitly add their addresses to
a whitelist using obscure knowledge that is specific to
a particular list or software or moderator, and completely
unrelated to the knowledge required to contribute to the list,
imposes an unacceptably high barrier.
But if we somehow made this process uniform from one list to
another, spammers would just add themselves to the whitelist.
p.s. though it is intriguing to consider - what if the instructions
for commenting on a draft were embedded somewhere within that
draft, so people would actually have to read it before commenting?
