Yes! The sidebar has been FAQed!
Our faq has 18 questions in it while faq-proposed has 40 more. What questions should move there for easier access for people unfamiliar with the workings of meta?
I'd also mention that the faq has some rather dated material in it that could get a good looking over.... like What should our FAQ contain? and The Six Subjective Question Guidelines -- Enforcement Notice (which I hope we've largely come to accept) or Why has this question converted to Community Wiki? which is completely out of date.
Similarly https://softwareengineering.meta.stackexchange.com/q/1646/40980 should likely get a good look and update.
