One thing that strikes me is the frequency with which I see the expression "software glitch" being used to underplay huge issues in process, design, implementation, analysis, testing. I don't know what the word "glitch" suggests to a native English language speaker, but to me it sounds like an increasingly abused way to hide the reality of the issues involved.
