Some additional thoughts and quirky facts
How about setting up a Usability Commission at the United Nations or the W3C? And they start knocking up standards?
Also, did you know that baguette was one of the first usability-aimed foods? It was developed specifically to enable the Napolen's soldiers fighting in Russia to stick the loaf in a special trouser pocket, so they can still march on and have more space in their rucksacks for warm clothes.
Similar with the Cornish pastry: the thick 'rim' was used to hold it with dirty fingers and eat up the filled centre, then throw the rim away. Or a carrot: the orange variety that we know is originally developed by the Dutch for patriotic reasons.
So, usability is already around us, we just need to back to our roots and start simplifying the tremendously complex world around us. Or we will breal down.
