I did it when I worked in that position for the Chicago Sun-Times; my colleagues followed suit at various points.
Yet perhaps it has never been done with the unfortunate visibility that some poor Web editor achieved yesterday at my former rival, the Chicago Tribune.
Someone there published a front-page story on the site that was clearly a dummy story, titled “Headline test here” and featuring dummy copy along with a picture of a gray kitten.
The team noticed it within minutes and issued the following apology via Twitter:
We apologize for the error on our home page. We are looking into what happened.
