There seems to be a bit of a learning curve when users first start using the site as we've seen with the OP adding an answer rather than editing their question or responding with a comment. I've seen a few different sites that offer some video tutorials offering quick intros along with some dos and donts.
I've seen the videos be a part of FAQ pages, part of a training page, and also included at the end of the registration process before the user would try to begin asking some questions, etc.
Why not create these videos for the trilogy sites?
It's quite obvious that folks feel pretty strongly against this. The comments and answers on this thread are all self reflecting and don't seem to place much thought about how others may or may not interact with the site. In fact, I agree with much of what people have said here, but this really is not about me or you, it is about the noob who may not know how the site works and never reads anything (like FAQ)...
I'd apply the following metaphor that really sums up my thoughts...
If you buy Madden 2010 for the XBox, you can simply pop the game in the XBox and grab the controller and start playing. You can open up the box and read the 42 page booklet on how-to play the game, or you can watch some of the game demos and go through the training modules embedded into the game. You can do 3 different things in this scenario, choosing the one that fits
I'm simply saying that if you apply this metaphor to the SO sites, we only allow you to simply pop the game in and start playing and provide the booklet. Why not the 3rd offering?
