More in reply to the comments than the original article.... In my experience no developer ever actually imagines that their code could possibly have bugs. Yes yes, they will say that of course all software has bugs, but deep down they know that that doesn't mean their code, just other's code. Turn all that code into products and that means when something goes wrong it isn't the product's fault. Therefore it must be the user's fault. Error messages can't possibly explain the problem, because the product can't know what the dumb user did. So don't bother really trying. This from the perspective of someone doing customer support.
