I keep seeing complaints like this with Slack and I think it's because teams need to focus on setting up the right rooms and the right conventions to go with those rooms. Then relentlessly explaining, encouraging, and enforcing them to keep everyone in flow. As one example, to cut down on DMs, each of our team members has their own room where people can "drop in" messages asynchronously. This means there's no notification and no expectation of immediate response, but that's a good thing because we use an agile process where people should be able to focus on their daily goals without distraction anyway. DMs then become a rare & discouraged channel only for emergencies and sensitive conversations.
