[OSGeo-Discuss] OSGEO & OGC spec development

Also remember that OGC has made its Mass Market Working Group  
discussion list public:

This is the best way for non-members to get in on certain  
discussions, particularly the ones Jeroen mentions. That allows  
individuals to put forth their opinions. A unified OSGeo opinion  
would certainly carry more weight, so I think it's valuable to move  
that discussion forward.
