Ask Fedora is a community knowledge base and wiki and designed to be the primary place for community support in Fedora. It is powered by Askbot. Rahul Sundaram has explained the history of the project here. We are currently running a staging instance for your feedback. Ask Fedora will have a soft launch by end of September and will do a full launch in sync with Fedora 16 release schedule.
Rahul Sundaram initiated a earlier effort for developers to directly answer user questions as part of the Fedora Weekly News. This effort didn't scale and is now defunct
