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. Ask Fedora has already been launched quietly but will advertised more widely in sync with Fedora 16 release schedule.
If you have any feedback on Ask Fedora, you can directly post a comment or question to the site and tag it as "meta". You can also join us at #askbot IRC channel in irc.freenode.net or post to Fedora infrastructure mailing list. Do read the standard operating procedure if you want to help with infrastructure of Ask Fedora.
Rahul Sundaram initiated a earlier effort for editors to interface with developers and directly answer user questions as part of the Fedora Weekly News. This effort didn't scale and is now defunct.
