It also probably has a lot to do with what kind of software you're developing. In my case, we were writing firmware for prototypes that cost over $2000 and were easily destroyed by bad code. That's bad, but not nearly as bad as code that could endanger human life or perhaps code that handles large financial transactions. If you're just developing a web application or twitter client, it's probably not worth being so anal-retentive about it.
