diaeresis (plural diaereses)
1. (orthography) A diacritic ( ¨ ) placed over a vowel letter (especially the second of two consecutive ones) indicating that it is sounded separately, usually forming a distinct syllable, as in the English words naïve, Noël and Brontë, the French haïr and the Dutch ruïne.
It makes perfect sense to use the diacritic in this way and it is part of their style guide, has been for some time.
You couldn't even spend the time researching what you're complaining about. Talk about pretension.
Still pretentious :-)
Yes, there is. A) it is a perfectly grammatically and orthographically correct usage of the di B) There is no prescriptive body which governs usage of American English - there's no need for an "excuse" to use an orthographic feature of the language as if it is some clause violated.
The reason they do it is because it's the New Yorker. It's their house style. It's what their readers expect and understand and it has become a tradition and perhaps even emblematic of the magazine and its brand. Complaining about the "pretentiousness" of the New Yorker is like complaining about the convoluted commands in eMacs or vim - it's not a problem, it's a feature.
Good writing reveals something about the reader. Bad writing reveals something about the writer.
However since you now seem to agree that it's pretentious, which was my original point, I'll leave it there.
We get it, you don't like the style of the article (and you might not like the style of the New Yorker), but why does that matter? The article used paragraphs, was free of grammatical errors, and was highly readable.
Different forums have different conventions, and judging by the downvotes even flagged OT is not OK here. I've learned my lesson.

Those extra accent marks make it much more readable. Without them, I always mentally pronounce "employe resume" as "employee rezoom" and then backtrack to correct myself to pronounce it as "employee rayzoomay".
