An interesting phenomenon I've seen around Swikis is that sites/pages
that are well organized are also long lived. Quality creates discipline
- nobody is afraid of ruining a page that's run down anyway. So I don't
think Swiki and quality content (for newcomers or otherwise) are

Note that Richard gave good detailed advice. About collections, you
*might* want to subclass them *iff* you are interested in creating
another collection. What I meant is that most people aren't creating
collecions - a library is there to be reused. If you are creating a
model (car) don't subclass Collection because you have multiple wheels,
just instantiate one.

Ok. Hope you can help us.
