Here’s the thing. I read a lot of news articles on technical subjects, and so I’m extremely aware of all these patterns (so much so that I expected, before reading this article, that I would have a lot to add); but, I can’t possibly be reading as many of these as the people who write them for a living. Occasionally I see an author whose work I respect move to a different context and start making these mistakes. Are they being enforced? Are they just popular because they are easy?
