Thanks for the suggestion.
We are planning to open up the online documentation and resources to community contribution similar to a Wiki. People will be able to come in and add comments or further details in the topics very much like the Community Content in MSDN. I do not yet have an estimate on when we will be ready with this but just wanted to let you know that it is on our ToDo list.
