Hi Nicholas,

I think, though, we should try to push as much as we can into the Scheme 
Cookbook.

     http://schemecookbook.org/

I agree that there's a need for more example-driven documentation; that 
documentation, though, that it doesn't necessarily have to attach directly 
to pages.  The feature that worldforum provides --- attaching annotations 
to pages --- does seem really cool.  Still, it's one more "moving part" 
that depends on WorldForum being always around.  If the Scheme Cookbook 
can do what we want, then why not use it?
