Why I Hate Slack and You Should Too

Sounds like more of a complaint of informal instant messaging in general, rather than a problem specifically attributed to Slack.

Slack has it's problems, but it also has it's place.

For the Slack teams I'm a member of, we've got rules about using @channel and @here, and anybody that uses either is usually shamed to some extent if they do so.

For the complaint about the use of Electron (and all of that overhead), it's trivial for a Slack team to enable the IRC gateway (in /admin/settings#gateways) and connect through your preferred IRC client.

To me, Slack is just IRC without any of the fun. I was encouraged to join some rooms for work, but then 1000 notifications later I realized that nothing of value gets discussed and that our boss was also invited, so he was seeing all the irrelevance. Turned off notifications and ignored the whole thing. No-one has brought it up since.

Another 'new' thing that is an old thing with added irritation.

I agree with the author. What he writes can also be said for something like Telegram when used as a coordination tool in a working group (no archiving, no threading, no tagging of important messages, no like button to replace a deluge of useless +1 messages)...

Maybe Discord is a better choice. I mean it almost feels like a forum of sorts. Just that they market for gamers and all kind of redditors use it.
