We're in an odd situtation as Stack Exchange has long-established communities and so has Ubuntu. We need to ensure that we communicate best practices to the existing Ubuntu teams.
How do Ask Ubuntu and Stack Exchange work?
Asking good questions
Giving good answers
Keeping the site useful and running smoothly
Integration tips for Ubuntu teams
Spread the word
One thing I would caution against is just pasting in a bunch of questions from an already existing collection of frequent questions. The Stack Exchange engine seems to work best when participants are asking questions they really are trying to answer.
In my experience many of the questions in traditional FAQ listings tend to seem very hypothetical (even when they are not). Please don't take this as some kind of blanket statement (I find such statements are rarely useful, and I'm not a Stack Exchange expert user) but rather an encouragement to focus on more individual and more interesting questions.
On the Stack Exchange blog there is a post from Robert Cartaino (the Stack Exchange community coordinator) where he comments on seeding a site with questions. Although the Ubuntu Stack Exchange is now in public beta, I think the comments there are still relevant. In particular, two comments stand out to me:
Jeff Atwood also wrote about early questions in a post about the launch of the original Stack Overflow private beta.
I will attempt to illustrate with a couple of the FAQ-style questions that are listed under the kernel tag. I think these questions are slightly awkward in the Stack Exchange environment because they really don't have a question body.
In any case, the two questions are about communicating with the kernel team and getting involved with the kernel. Here is how I imagine those questions as if an individual had asked them. I won't presume that my suggestion is particularly good - it still feels very 'invented' - but hopefully it communicates what I was trying to say.
