It's surprising that so many developers install the notification stuff for these sort of things. Why would you consciously sign up to be interrupted during the work day?
Slack is especially bad, as it has no filters whatsoever. Looking over at that tab in my browser, it always has an asterisk next to the icon, and usually an exclamation point telling me about a Very Important Direct Message that is invariably somebody in another timezone saying "Good morning @channel!"
It's the sort of thing that deserves checking a few times a day. Why you would configure it to pop up desktop notifications or make noises on you phone is beyond me.
