100% agreed. When I want to focus on something I simply shut down Slack.
I have all notifications disabled by default, and recently quit using the desktop app too, since it’s impossible to get rid of the little red circle, even when you have notifications off.
I believe that messaging can get very ineffective, especially when overused.
Great point with the “addiction”. I see that people write each other on chat even when they are sitting next to each other! What is it, if not addiction?
