You talk, but what do you actually *suggest*?

Talk is cheap. You use to do the walk too, but you've already said that
you're not interested in that any more. So excuse me if I'm not impressed.

The thing is, bugzilla is totally broken because it's designed to help
track bugs, but it's *not* designed to actually handle the much harder
problem, which is to actually get the *right* developers to be aware of
the *right* bugs!

And both of those "right"s are important. Spamming everybody will just
mean that everybody tunes them out. And spamming even the right developers
with useless bugreports will also just cause them to tune out the good
ones.

The thing is, the "tracking bugs" part that bugzilla _can_ do is also
totally _useless_ without that much more important phase, namely the
"connect the parties". That's what you really used to do. You made
developers connect to the reports, because your reports were _useful_ and
not overly noisy.

But go back and look - did you notice that once you connect the dots, it
turns out that bugzilla itself isn't all that wonderful. Quite a lot of
your regression reports had other ways of pointing to the problems,
including very much mailing list archive pointers etc!

So bugzilla isn't actually all it's touted to be even _once_ the
connection between reporter and developer has been established. I really
don't see why you are so hung up about bugzilla, when your own regression
reports didn't generally point to it all that often!

(I just went back and double-checked: you had more than twice as many
pointers to kernel mailing list archives than you had pointers to bugzilla
in the one series I looked at. And I'm _not_ saying that's wrong at all: I
think the mailing list is actually likely to be at LEAST as useful as
bugzilla is as a bug-tracker!)

And bugzilla actually falls down even more than the mailing list does for
the whole (and MUCH MORE IMPORTANT!) phase of connecting developers to bug
reports. And THAT is really the problem here.

And no, I don't actually think that automatically closing entries that
haven't gotten any attention in the last two weeks would "fix" bugzilla.
But I think that it might actually make people
(a) more likely to look into bugzilla (and thus maybe improve the
"connecting" developers/reporters thing)
(b) act as a trivial noise-removal thing, because it would give
preferential treatment to people who are diligent about their
bug-reports and are willing to follow up on them and it would also
remove the noise that comes from obvious things that broke and got
fixed.

But I think the real fix is to have real humans that help de-noisify the
bug reports. Let's call them the "bunk" group, just to pick a random
four-letter combination. The kinds of people who help turn the mindless
noise that is bugzilla (and the kernel mailing list) into directed
_information_.

No, nothing is ever going to be perfect. And "filtering" the noise will
inevitably also end up dropping real information. But not filtering it
will guarantee that even more is dropped.
