What you are saying is good, and I would like to extend what you posted 
with what follows. IMHO we are trying to focus too much on what it was 
wrong to forget what it was already good, like if what was already good 
in the distro would be granted by default (e.g. trying to focus too much 
on what is already in ANY of the 100 distrowatch.com distros: all of 
them have the same core-packages on the other hand] to forget what is 
was already good or better: e.g. good support for extra hardware, better 
support for scientific applications, etc.).

We should summarize what there is from what there isn't in the distro. 
The 2nd problems is that we seem assigning to most packagers and 
maintainers some secret powers that they should have, like knowing the 
package better or at the same level than upstream developers. If not, 
then there are lack of resources...; maybe they just know how to 
assemble and compile it...and that's all. IMHO knowing the package at 
such high levels has become the exception, not the rule. One 
packager/maintainer might know very very well 1 or maybe 3,4 packages 
(e.g. colin for pulseaudio, buchan for samba, me for tex and so on), but 
there are 10000 packages out there and there aren't 5000 maintainers...

I give you an example. In MDV 2010.0 or 2010.1 the kdenlive package, a 
video editing application, was not working at all. It crashes on basic 
stuff as soon as you open or import a video file. In other words 
unusable. How was possible that? Well, one might say poor QA, bad 
packagers, bad maintainers or no maintainers at all, or no QA at all. It 
your fault, it's their fault, it's our fault. Indeed it doesn't matter. 
The main problem is that we rely as main source of QA the bugzilla. So 
what is reported on bugzilla has a bug that we should fix, what there 
isn't should work by default and has automagically an higher QA score. 
IMHO this is a false assumption. I might find it crashes and be lazy and 
not doing any bugzilla report, or I'm not sure about what to tell 
exactly, because maybe I think it's fault of my configuration, and so 
on. In the specific example backports have a working kdenlive (maybe 
it's just luck, dunno) but according to the supposed QA score the 
kdenlive in main should be better than the one in backports. And indeed 
it isn't because any program barely working is better than any program 
crashing on startup.
To solve this there are a lot of solution, but it's not said that the 
one or the other should influence people to use this distro and not 
another, like we might think. E.g.

1) We might move kdenlive from good main to evil contrib or remove 
kdenlive from the distro? Well, a non-existing package won't crash. And 
so distro would result more polished, ordered (I like ordered and 
cleaned distro with no broken deps in hdlists, really) should rock. But 
from point of view of an end user he don't have any video editing 
application anyway. So who cares of the others packages he won't use?

2) We might let people know that the backport version works. So more 
communcation here.

3) We might add several new rules and weights on the shoulders of the 
maintainers/packagers. A packager could fly away, so letting these rules 
on the shoulders of the other survived packagers which then will be more 
overloaded, and then could fly away more. Sound a bit like the 
"highlander" packager...

4) We might help to let these rules easier, lighter and quicker to be 
implemented (more communcation, self or packagers helping each others, 
more automatic tools)

5) Add a precise protocol of testing for each package. This might be 
automatic or manual (or both). In case of manual, the testing protocol 
steps might be performed by anyone. But shouldn't go in the destructive 
spiral of more rules. Documentation should be crystal clear, and 
information should be easy to catch not let users waste days and days 
trying to find the right thing to do, in seeking good documentation 
between tons of obsolete and bad one. Also the report of the testing 
should be easy to post, not opening 27 sites, scroll between 18000 
packages, wait 10 minutes the server answers, or sending 84 mails and 
wait answer from 54 different people...; In case of kdenlive, a basic 
protocol test could be like this: 1) install the package 2) Go on menu 
Project/Add clip and open the file blabla.avi HERE... 3) Go on menu 
Monitor/Clip and click on the button "play" 4) ... 5) rely also on the 
upstream protocol testing if exists 6) report it works by a couple of 
clicks. This won't require specific skill and even users who might not 
have ever used this package could partecipate.

5) Punish the one who uploaded the package. Blocking it for one lap. 
Well this is a bit scaring ;-) Don't do that.

6) Any combination of the above.

Second problem is that  there also any referring to documentation 
support, but speak only from point of view of packagers. We might have 
things that are rock solid, but if nobody knows how to use them... ;-)

Bye
Giuseppe.
