I think it is high time I change my name to oops! I can not imagine anyone makes more mistakes and generates more glitches than me.
For several years I was a beta tester. My job was to find all the glitches and report them. I was really good at it. I paid attention to detail. I could tell you how many key strokes it took to do anything. I could tell you when you should use the mouse and when the keyboard was the best option.
I miss those days when quality mattered and things were tested and actually worked when they came out in production. It was satisfying knowing the product worked before it went to the masses. I miss that part of my job.
