You tell me what I should spend my time working on, and I promise to
do it OK? :-)

For example, if I have a choice between a TCP crash just about anyone
can hit and some obscure issue only reported with some device nearly
nobody has, which one should I analyze and work on?

That's the problem. All of us prioritize and it means the chaff
collects at the bottom. You cannot fix that except by getting more
bug fixers so that the chaff pile has a chance to get smaller.

Luckily if the report being ignored isn't chaff, it will show up again
(and again and again) and this triggers a reprioritization because not
only is the bug no longer chaff, it also now got a lot of information
tagged to it so it's a double worthwhile investment to work on the
problem.

I think a lot of bugs that "aren't getting looked at" are simply
sitting in some early stage of this process.
