A couple of changes to note

[Dimitris Symeonidis]

Regarding the automated reminder and closing of bugs, I think you are
missing one parameter: In your thought process, you're assuming that
bugs marked for expiry are correctly marked so, in the sense that the
reporter(s) were asked to provide extra info and did not respond.

However, from my experience, a small but not ignorable percentage
(maybe in the order of 10%???) of these bugs are wrongly marked as
such:
a) the reporter provided the info requested, but no one ever changed
the status back to new/confirmed
b) the reporter was asked to try with the latest ubuntu, and has
reported that the issue has been resolved, but no one ever changed the
status to fix released

It would make us look rather silly if in all these cases we start
asking "please provide the info requested"...

Also, in any decision about closing or leaving open as incomplete,
please take into account how this affects the bug statistics we are
measuring (Daniel Holbach)

Just my €0.02
