"Picking your nose is intuitive. Much like Kleenex, pinch-to-zoom is intuitive only in retrospect."
I respectfully disagree.
I happen to think the Kleenex metaphor doesn't work very well. Kleenex is generally for wiping your nose not picking it. Wiping your nose, I have to say is an intuitive reaction to getting snot on yourself.
Also, doesn't "intuitive" in the context of software or UI just mean easily learned or understood? Which is sort of what Timoni West is saying. I don't think its necessarily a myth to design something that is easier to learn or easier to understand.
Here's Jef Raskin, writing essentially the same thing 20 years ago: http://www.asktog.com/papers/raskinintuit.html
I wrote a blog post about this topic. It was an epiphany for me, to realize that simple, intuitive interfaces are not always the goal.
Complex, learned interfaces can be much more powerful.
If we're using the word 'intuitive' the way you've described, striving 'above all else to make your interface feel intuitive' is not only bad practice but likely impossible. In developed societies we learn new behaviours starting from birth, and by the time we're independent what feels 'intuitive' can be completely different. The word intuitive isn't a myth, it still applies, it is just based on an improved media literacy.
