I think being able to community add to the API docs would be very helpful.

For beginners http://dcsobral.blogspot.com/2011/12/using-scala-api-documen... may be helpful in learning how to navigate the docs buuut what really helps are examples especially with scala's sometimes long and hard to parse type signatures.

In general I think a site for language docs where people can add comments/examples/content would be extremely useful. Like the php docs but for all languages in the same place. I never use php but comment-able docs are a win.

APIdock (http://apidock.com/) already has the “commentable multi-project documentation” infrastructure in place, though it only has the Ruby language and two Ruby libraries on it right now.
