Its a great place where you can ask questions and get the answers from teams across the organizations and build knowledge base along the way. I really like the suggestions for previously asked questions. You can always refer the person to the previously answered questions and you don't need to go through the effort to identify the issue and answer again. Integrating it with other knowledge tools is also very easy and you can create a AI chatbot around the knowledge as well.
I like the ability to document organization-specific processes and builds. The Slack integration is also helpful for keeping track of other contributions or questions.
