Pins 2&3 reversed???

This is my default:

  3
1  2

I think I've seen 1&2 reversed occasionally.

The only time I use something else is with SOT-23 diode & LEDs, where I use A&K & have 
an appropriate modified footprint.

  When you organise your footprints, what pinout do you use for SOT-23's?

  Do you organise the pins...
   -like shown in the attachment?
   -or with pins 2&3 reversed?

  The bigger question really is: Where do you derive your pin numbering
  guidance from? 

  I find that some datasheets just show the pin names against the actual
  pins (& cutout the middleman of *numbers*) thus avoiding the issue
  altogether. This doesn't help those of us who want to be able to use a
  common footprint across multiple designs.

  One answer is "define your own company standard", but if I chose
  against an industry standard, that'd be a bit silly wouldn't it.
