Wikis are great because they make information available. Stack Exchange is great because it makes asking questions easy. I'd like to see how the two can be put together, so that people can ask questions in a Stack Exchange-like format and the answers can easily be migrated into a wiki.
Is there a Stack Exchange-type extension available for MediaWiki?
I've seen WordPress MediaWiki integration. Ideally I'm looking for a introductory guide, also explaining some options.
Furthermore, I'm looking for people's experiences with this and their advice.
