The Operator's Manual

While reading this article I came to the conclusion that I am guilty of doing such things as stated in this article.  At times I thought I had enough commonsense to operate or use something that I've never used before, but After fumbling around and almost killing myself I would read the manual.  This is where I became confused because the instructions were vague and now I really had no idea what I was doing.  I would think that many of us go through this in our lifetime and wonder, who in the hell wrote these instructions?  

It seems that bad things happen to good people which this article points out.  I know that technology is changing even faster than before, but it doesn't seem like this should be an excuse for bad writing of instructions.  One of the things that appalled me even more is that after all of the legal proceedings they are using the same manual for teaching a class on how to use the studgun.  It's funny someone pinpointed out the problem, but no one ever went back to fix it?
