I see: the old how-long-should-an-article-be question. I use The New York Times as a guide. If you were to look at the online version of today’s front page, you’d see ~45 articles. 90% are 6 minutes long or less. 9% are 7-9 minutes long. One story, a profile of the former director of the Centers for Disease Control, is 22 minutes long.
So if you believe the NYT, readers are willing to spend up to 6 minutes on a story. They’ll sometimes stretch it to 9. The Times thinks it can only occasionally snag a reader with a longer piece. But it can be done, so the Times publishes long pieces. If you think the Times knows what it’s doing, you’re entitled to do it, too.
