In my mind SD had little to do with normal distribution other than we are familiar with the SD in a normal distribution covering 68/95/99.7 in 1/2/3. Having said that, the SD is equally spaced along the normal distribution - is this what you mean? I.e. that the SD somehow defines the normal distribution? I need to think about this one...!

OK, so the gaussian/normal distribution does seem to naturally use the SD/variance as part of its description. From what I've read the mean absolute deviation is related to the SD by a constant for a given normal distribution.

I found this interesting discussion on stack overflow:

especially about the euclidean/manhattan and minowski distance.
