Yep.

Well, I for one can't currently suck the end of the fire hose which
is -general, and would be less able to do so should other lists be
folded into it. So I lurk on -bugs, -performance, -admin, and
others -- not to glean information so much as to attempt to respond
in areas where I feel I might be able to be helpful and, with a bit
of luck, take some of the burden off of those who do the most to
help people on these lists. Combining lists will only make it
harder for me to attempt to assist in this way.

I don't believe you. Scanning this:

http://archives.postgresql.org/pgsql-performance/2010-05/index.php

I see a few non-performance questions, but they're clearly a small
fraction of the traffic.

I think that's exactly backwards -- we shouldn't have any traffic on
-general for issues which could reasonably happen in another list.
You can always configure your email to combine lists into a common
folder upon receipt.

MySQL has a bunch of lists, none of which get much traffic. Honestly,
they should probably be combined.

"They" was referring to the various low traffic MySQL lists which in
my opinion does not work. As far as Linux, when I briefly subscribed
to the kernel mailing list there was such a volume of traffic that it
was difficult to manage as a noob.

I do not have an opinion about PG. I think that those two examples
could be seen as how not to run email lists effectively.

Sure, if we have distinctions which make sense then having separate
lists makes sense. Linux has separate lists for different drivers,
different parts of the kernel, projects to improve the kernel in
various specific ways (latency, etc). I'm all for having a list
dedicated to infrastructure (oddly named -www here) and a list
dedicated to printing flyers and arranging conferences (-advocacy)
since those topics are usually well defined. Lists like -ecpg or -odbc
would work fine if the traffic warranted them.

But some of the lists we have now are 99% overlap with each other -- I
claim because the definitions are meaningless. What part of postgres
discussion (aside from this thread) *don't* relate in some way to SQL?
Or administration? Or performance? Most performance problems end up
being solved by adjusting SQL or changing GUCs. Mot administration
questions are originally posed as general help questions. If you're
subscribed to these lists you get a random, fairly small, subset of
discussion related these topics.

Perhaps what I'm looking for is a more sensible division that allows
most of the traffic related to the subtopics to actually go there. It
would have to be a division so clearcut that anyone who doesn't follow
could reasonably be blamed for not following etiquette. That's simply
not true with the current divisions.
