I didn't mean to imply that troubleshooting was not a useful skill. Like
you, I've done a fair amount of alien legacy code maintenance (although not
99%); my views are very much coloured by this experience ;). I think it's
clear, though, that a tendency to rely on debugging as an alternative to
good design is not a desirable attribute in a job candidate.

I've occasionally run into something like this. Occasionally there is a gulf
between what I consider "Best Practice" and what is actually going on. Years
ago I probably would have frightened them; in my dotage I've learned
diplomacy and I figure I can help them. I love mentoring... it's how I learn
too. Is this arrogance? Not sure. I consider myself a craftsman; I'm proud
of my skills, certainly.
