To address the idea of a tutorial to get new users started: we have something like that already in place in the Fresh Meat forum. There is an "Adopt a Newbie" program available there for new users who are interested. I was an adopter for a while, and I prefer that method to a built-in tutorial, because adopting/being adopted is much more personal and engaging. Its a nice way to make new friends, and it encourages the community spirit that is so important to us here. :D
