What about this
http://www.arduino.cc/en/Tutorial/ShiftOut
That cap on the clock signal is wrong, we all know it, we respond to questions about it every second day, and yet apparently there's no way to fix it. I admit I've not tried because everyone said you couldn't edit it, is that correct?
At one point, I suggested that the reference/tutorial section be set up to be user editable like the playground (wiki), but that was apparently not accepted by the Arduino crew. 
edit: I am a little surprised the forum moderators and administrators do not have edit ability in that section. Since that known error has not been changed, and many know of it, there is a word I use for that situation: LAZY.
BTW, that is aimed at the person who is responsible for the maintenance of that section of the website.
