If you want to tell everyone in your company something, you could email them I guess. Is it the fact that it's a "chat room" which means you expect it not to work? What's best, here? SMS? Email? Putting something on the website and making everyone check the website once a day at noon? Tell one in ten people and get them to "pass it on"?

Is this a serious question? Companies have been using email for internal announcements for decades.

Yes, and he's making the point that it manages to work. And that perhaps your expectation should be the same for a chat client as for an email client. Which may or may not be a valid point.

And without proper mailing-list-moderation, that too can cause email storms. No one blames "the genius who decided to put everyone in one mailing list" when that happens.

The real fail here isn't putting everyone in one channel. The real fail is not using/providing proper admin tools

I'm going to guess you could also break IBM's phone system by attempting to start a conference call with 200K people on it, and destroy their auditorium by putting too many people on the stage.

We definitely blame the genius that didn't BCC an email with hundreds of individual emails (when a mailing list isn't used)

[ghaff]

Although usually only a limited number of people can post to an "announce-list" that goes to everyone in the company. (And if there are company-wide lists that anyone can post to, most users filter those to a folder. I suspect such lists don't scale past a certain point either.)

Most companies today have a decent intranet site for these things.
