Earlier quoted context omitted.
I'd put "jokes" and "cultural references" together under "tone". Recent articles often feel like they're trying to catch the attention of children. There are lots of "candies" to make you read: pictures, GIFs, jokes, an attention grabbing title, colors, emojis, a friendly tone, lots of exclamation marks. On the other hand, that article is mostly black on white text, that's plain in a good way.
That's because young people have very short attention span and they must be fed with instant gratifications all the time to continue reading. Those "candies" are targeted at them.
Don’t old people who sit in front of the news get a similar rush?
