<i>All interaction is learned. There is literally nothing that is obvious to the unexperienced thats not the discussion here.</i><p>But there is a scale of how easily something is learned, and a UI with more or better affordances will be easier to learn than one with worse or fewer affordances.<p>As someone who designs a lot of UI, I was nodding through much of this article. The most obvious part I disagreed with was the idea that they are at least making things more attractive as they damage usability. If those comments referred to the current trend for bland, homogenous, flat UIs, then I find most of these much less attractive than those we had just a few years ago. Almost everything looks the same now, and that look is so dumbed down that to me it feels like the digital version of painting a big canvas solid blue and then selling it for $100,000 as &quot;modern art&quot;.
