Overall I think this is great, really well done, kudos all around.
One caveat though, the call to action at the end is
Getting started is easy: just ask or answer a question, and start building your reputation today!
Which is ... not really what you want new users to be doing.
Ideally they should spend some time browsing the site, reading the list of questions and the sorts of answers that do well.
I realize that "hey, go browse around a while, then think about what questions or answers you can contribute which might fit well here" is not as strong a call to action as "Go ask right now!" or "Go answer right now!" -- but it's much more likely to result in a user who doesn't get a question closed or downvoted, or an answer ignored or downvoted.
(Immediately jumping from "hey cool site let me view the quick start" to asking a question is particularly inadvisable. If nothing else, reverse the order and suggest they try their hand at answering first to get a feel for what questions and answers work well.)
Official response: status-completed We tweaked the wording to:
Interested? Take a look at some new questions and see if there's one you can answer, or ask your own!
