It would be nice if I can filter apps based on these labels while browsing the App Store. Or even determine which of my existing apps fall under which label(s).
I don't think one person would make a case study. Whatever his reason is, it would be a very specific personal reason. A case study of this will be just be like profiling a patient in a lab.
I agree with your premise. But I think when it gets momentum and gets picked up by the news media, there will be lots of 'explainers' on TV and the web.
We can say that any of these professions will gradually evolve to accomodate programming of some sort. I was thinking about this and I realized that putting programming in front of someone like a winemaker will also have to deal with problems faced by programmers--debugging, refactoring code, upgrading, optimizing, putting together frameworks, and etc.
I had my Canon DSLR body cleaned at the service centre here in Brampton, ON. When I got it back I noticed it felt different--the shutter sound is more thumpy, and etc. I checked the serial number to check if it was really mine and it was. It's all fine but then months later just by some coincidence I saw a photo on Flickr with my e-mail address in the metatags. Some of my photo buddies warned me that Canon is notorious for swapping parts when your cameras are in for service.
I did not have any problems with how different the Mac App Store UI is and how it's inconsistent with the other Apple programs. Same thing for the Twitter app. It looks different, yes. But none of the points in the article made it more difficult for me to use.
