Hi Robert,
Thanks for the constructive ideas :)
At the Capital team meeting held at the JWC15 we talked about also taking in alot of the posted ideas from the Google Groups debates and form a idea pool to continue working with.
Its some good ideas from you too - the 2nd one would be a "Wikipedia modul".
I think at this point we have seen atleast 8-10 other models from the community from membership based over massive changes to the JED and into different advertising ideas.
In the coming weeks i hope we can collect and describe them and end up with some solid ideas and concepts to continue working with :)
