I do my best. I usually have so few bugs in my final ship products, that it's not worth it to have a tracker.

Getting there, though, I have lots of bugs. It's just that I want them gone, before I pat my app on the butt, and send it out into the field.

I often see people use Voltaire's phrase "Perfect is the enemy of the good," to justify writing bug farms. I'm not sure that this is what he meant.
