It is unlikely my opinions are going to make the slightest difference  []

BTW, I once had an ASIC design engineer working for me who point blank refused to draw NAND gates as inverted input OR gates, or NOR gates as inverted input AND gates. He always did a little mental gymnastic to figure out the logic of the circuit. I gave up trying to persuade him to change because his designs nearly always worked first time!

There seems to be a correlation between brilliance and perversity :-)

Years ago I was completely converted to using the DIN standard (used in Germany a lot) for logic gates rather than the US ones. They are MUCH more compact and, once used to them, give a better intuitive feel. Complex gates are a doddle with them too.
