That is a good question. We formerly used Confluence with the Questions for Confluence add-on for our Community. Now, as our Confluence Product manager explains on this other post, What is the future of Questions for Confluence?:
...the decision to move Atlassian Community to a new platform was the result of the broadening requirements of the Community. That is, the need for the Community site to encompass more than Q&A, and also to offer things like user-generated articles, product-specific landing pages and topical themes, which aren’t currently part of the feature set of Questions.
Please let us know any follow up questions or anything we can help with.
