Is there a video that explains how Stack Overflow works and can be used? I.e. a short tutorial to get new users started. If there isn't, then the people behind this site or others who know how it works should make one, because it's overwhelmingly different from other sites and thus difficult for beginners.
No video, but...
We're rolling out a new "Quick Start" guide designed to help teach new users how we differ from other sites, and the absolute minimum they need to learn to get started and have a good experience.
We're testing it on our Ask Different site here.
I'm working on building one specifically for Gaming. You can see the latest, unlisted draft.
Speaking of which, I need a narrator :)
