Supporting Human Editors

I want to allow people to act as editors, selecting and ranking/positioning stories and pictures, edit and mark stories to correct mistakes or classified them with keywords.  Intelligent selection of images is especially important.  Ultimately, I want to allow human editors to form some sort of collaboration network with workflow infrastructure.  I am still trying to figure out how to achieve these goals while supporting both amateur and professional editors.

Professionally, I can see companies publishing newspaper sections dedicated to their industry sector.  Large companies will have enough news to publish weekly or even daily newspaper sections for their customers.  There will also be a large number of industry experts who would like to publish newsletters to be automatically inserted into people's newspapers on weekly or monthly basis.  Schools and governments have their own particular needs as well.

This area is where I need the most help with.  If you have ideas, suggestions, or comments on this area, I would appreciate it.
