The original email in this thread was a list of bugs listed in the kernel bugzilla that had
gotten "no attention". As it turned out, many of the bugs had gotten attention in email from
developers, and some of them had been fixed. Of course, none of this was clear from the web
site, which isn't sufficiently useful for most people who actually fix bugs to bother using
for serious discussion.
The issue with using anything other than email is that people will pretty much never remember
to do any particular thing other than reading their email, and they only really look at the
main content of the email. They'll probably ignore links and attachments. And what they'd do
is a bunch of research and local work, and then reply to the email. Anything that depends on
some other way of getting people's attention or detecting their responses isn't going to work.
