Slack is designed to replace all communication tools, but it can also be a distraction if not used properly. To use Slack productively without getting overwhelmed by distracting conversations, one should quickly catch up on conversations in Slack by using All Unreads, which shows all unread messages from all channels in one place. This feature allows users to browse unread channels alphabetically or by newest/oldest messages, and even uses "Scientific order" to prioritize channels based on importance. Users can also use Slack's keyboard shortcuts to quickly clear through unread messages, switch between channels, edit their last message, and more. Additionally, users can turn off notifications, rely on email notifications, and use features like Highlight Words and Starred messages to stay focused and informed. By managing and optimizing Slack channels, such as being picky about sidebar channels, muting unnecessary channels, and defining each channel's focus, users can reduce distractions and increase productivity. Ultimately, finding a balance between using Slack for team communication and preventing it from taking over work time is key to staying productive in the platform.
