Personally, I consider it my own responsibility to learn the terms. And I am learning them, I just have other stuff to do in the meantime. A "start here" would be useful and the place I started was the about page. Since then I think of a topic I think is relevant and then search OB and LW for topics already about that subject. More often than not, someone else has already said what I am thinking. That, mixed with reading comments, has gotten me as far as I am now.

Of course, a list would have made it a little easier. :)
