Slack affords a method of passive communication where waving hands or tapping someone on the shoulder is an invasive method of communication. Unless there's an urgency, or some complication that should be discussed in person; slack is the preferred method so as to allow the party you are interrupting a chance to change their focus in the least impactful manner. If I go to someone directly, I am losing 10-15 minutes of my own productivity + the length of the conversation and that's multiplied by the number of people I interrupted. Some people who I've worked with, love to have to have a face to face for questions or information that is not urgent and could easily be taken care of via slack. They seem to do so because they prefer to small talk, lament, debate or some other personal reason; they don't do it for technical reasons. If your team can effectively communicate passively, on slack, your on a team that has a foundation from which a remote-work policy can easily be enacted.
