Slack May Have Just Published the Worst Newspaper Ad of All Time (2016)

I'll admit, I'm glad we've moved past the open letter era, but as somebody that got hired to write a lot of them, I think the part the writer of this particular article got really close to understanding why this works was here at the end:

"But like too many other companies, Slack has been drinking its own Kool-Aid for too long. It seems the company believes it's the greatest thing to come along in recent years, and that it's irreplaceable. And that's a mistake. "Slack is here to stay," the ad concludes. Guess it's time to prove it."

The point of this kind of ad is, in part, to rally supporters, enthusiasts, and employees under a common goal. Given that it's 2022 and Slack is still the dominant player in the space (maybe Discord is an emergent challenge) AFAIC, it did its job.
