I personally completely agree with Neil's reply to the letter in Scribe-a-Line regarding Arduino sketch fritzing. As I have been messing around with electronics since OC71 transistors came in slide out cardboard boxes of five and having taught physics in the past I find a proper circuit diagram far easier to follow, but (isn't there always a but?) I have seen people mimic a sketch from a fritzed diagram who could not read a circuit diagram – mainly because they follow the physical layout of holes and pins which a circuit diagram does not show.
So basically it depends upon who you are talking to whether the Fritz or circuit diagram is the better.
