We can easily share with everyone and it is good for documentation as well. Stack Overflow also has documentation that helps us to be effective when asking questions and answering the questions as well. It is easy to use and easy to spread tips and tricks.

I enjoy the same features of Stack Overflow with my team, privately. It comes with easy documentation to set up the Q&A and Knowledge Base, and the Team integration will be used also.

It's very easy to ask a question to your colleagues or share your own knowlege Q&A. It has centralized our documentation so that I can take any question I have to our Stack Overflow and either find the answer, or know that it hasn't been documented. The markdown support allows for easy and pleasing formatting of questions and answers.
