I agree. As a remote freelancer, I'm currently in (checks the app) 5 Slacks. I have explicitly told everyone in each of those Slacks that I treat it as async only. I sometimes have it up, and sometimes don't when I'm cranking. I definitely don't have push notifications coming into anything. I've found being in Slack is a great way to feel less isolated, and conversations that might not otherwise happen happen. I also am in very small channels, usually no more than 5 people. This may contribute to why I like it. I can't imagine being in a 50-100 person Slack with everyone messaging everyone. Especially if I'm expected to keep up. The low population count makes it so that I rarely miss anything.
