I don't understand the point of all these stupid chat apps... Discord, Slack ect... If you need real time there is IRC. Otherwise, just setup a mailing list.
You're like that person who laughed about Hotmail when it came out, because why would you want someone else to host your e-mail, and why would you want to access it in a browser instead of via a full-featured client? There's a difference between being "wrong" (which you're not), and realizing that 99,9% of people in the world aren't you. IRC will never be used for corporate communication. IRC usage has been declining…
And, to this day, Hotmail is still significantly slower and harder to use compared to Thunderbird. The only advantage is that it still has emails that I received almost 20 years ago.
> IRC will never be used for corporate communication.
As recently as last year, we were using IRC for corporate communication where I work. Fortunately, I'm still able to use the IRC gateway with Slack, but I really don't see any real advantage to using Slack over IRC on a work computer that's always connected. My client's logging easily beats what Slack provides.

I don't think it's because it solved a problem about keeping in touch. It's just an advertising platform and the reason why it has a market cap of that value.
> Slack made the concept of IRC usable for "normal people".
A decade or so ago, I communicated with many normal people over IRC and Usenet. More normal people were able to use chat clients like ICQ, and the various messenger clients (AOL, MSN, Yahoo, Google).
I simply don't see why people keep saying that Slack and hosted chat providers like it are some new innovation that people can finally use when they've been able to do so for the last several decades.
