Yes, thanks, but I am already quite familiar with the idea that users will break and misunderstand any UI in creative and unexpected ways. That's why we do testing of any new UI designs. That's totally unrelated to my point.

My point is that the author writes as if something that is perfectly familiar to any mobile app user--and is literally the standard way to present a default option that can be changed--is something that has never been seen before. As I said, find me a mobile user who doesn't know what that arrow means in the screenshot in his article. He gave up all credibility with me at that point in the article. It may be that there's a story here, but either way this is just terrible journalism.
