Scoble says that every bug has a story in explaining why nagging bugs don’t get fixed. I’ll just add that sometimes the so-called “easy to fix” bug turns out to be incredibly hard. Run up against that a couple of times and you’ll learn to stick to the bug prioritization too.
Of course, I don’t have to like it just because I understand it. I once identified a bug, identified a fix, and convinced QA that my fix was correct. But the bug was still there two releases later - it just never became a priority.
