Actually, infrastructure is appropriately discussed on -sysadmins ... web
is on -www ... tends to be a bit of overlap since -sysadmins was added
later, and prior to that we did discuss on -www ...

I don't agree with the comment about 'if traffic warranted them' though
.... the fact that there is very little traffic should be what makes them
attractive / useful ... you don't have to weed through alot of posts to
find the odbc/ecpg related ones ...

how about something -sql vs -tuning ... ? -tuning replacing -performance,
which I do agree could be sql *or* server ... where -tuning would be more
obviously server related ...

Well, there's no free lunch. If we have a whole lot of "small" lists
there are going to be two big downsides: fewer people reading each list
(hence fewer answers), and many more arguably-misclassified postings,
thus diluting the theoretical targetedness of the lists.

If you want good answers to questions you need to post them in a forum
where there are enough people to ensure someone will know the answer
(and have the time/interest to respond). People who want answers and
don't want to have to read other discussions should consider obtaining
commercial support.

People can post without being subscribed, and most people around here
will CC them when they reply. That's supposed to be a feature of our
lists. Maybe when you receive such a question you can forward it to a
list CCing the person.

Not that I disagree with your opinion that a smaller list is desirable.
I think collapsing lists into -general or whatever would be a terrible idea.

A low-traffic list is a feature, not a bug. Most people don't *like*
subscribing to lists which have 80posts/day.

This is a set theory fallacy. While most performance issues are
administration issues as well, it is NOT therefore true that most
administration issues are also performance issues. In fact, I'd say
that the -performance list does an excellent job of sticking to
troubleshooting performance issues only. And for someone who has a
performance issue, and does not want to field 100 emails about "can't
install Postgre", that's a feature.

Only someone who is a postgresql developer would consider 15-30
posts/day "small". For most of our user base, the level of traffic on
-performance, -sql, and -general is already too high and many people
don't subscribe to these lists because it is too high. I get complaints
-- and people personal-sending me questions because they don't want to
subscribe -- all the time.

Having fewer posts on any particular list is *desireable*. It's a good
thing. It's *only* a problem when a bug report or user question goes
unanswered because the list is unattended. And so far, I've only seen
one report of that.

Yeah, that's because I was responding to the suggestion that 5 of our
lists should be collapsed into 'general' as the One Uber-List.
