To be fair, I wrote "new or exclusive", not "unknown to me".
The "strange etiquette" you mention is exactly what I was referring to. Except that, to me, it did not feel like a joke, so I wanted to be sure — I am probably not enough used to some aspects of American culture.
"2. The article explains a situation by giving a basic history lesson, and does not contain any new or exclusive information."
Doesn't hold in my opinion. The article is more than "basic" for anybody not following Ukraine permanently.
Still can I agree with you if you consider the article tone a bit insulting to the reader. I find it a strange etiquette, openly writing to the reader as he's "too simple." But I believe enough readers consider it a joke, exactly on the topic "most Americans don't know anything about the World."
