>but I've also known programmers who just don't care about striving toward perfect, bug-free code This target moves too much in business to be able to efficiently target it. I surely wouldn't take the time to make something perfect if I knew the business was going to turn around and add another feature that forces me to re-evaluate the thing entirely. While 400 homes lost is certainly significant, don't forget the millions of homes it accurately kept track of. Imagine the amount of work and resources that would have had to be used to keep track manually and by paper. Please don't worry about 2 steps back after you've taken several billion steps forward.
