Slack provides a quiet zone that eliminates distractions like ad-hoc conversations and sounds that can disrupt focus, allowing people to work differently according to their personal needs and spaces. Slack also enables asynchronous and remote collaboration through features like direct messaging and posting of updates that allow humor and culture to develop within teams. While not the only communication option, Slack's media features provide an effective medium for virtual work that supplements in-person interactions like conferences and collaboration spaces.
