I actually really like the fact that we are public domain. :) It allows us to freely distribute our content, and we are covered legally as long as we acknowledge when we use fair use or other copyrighted work (government public domain documents do it all the time). I think the licensing mixups about the other language editions could be related to the fact that when a new MediaWiki is set up, it automatically defaults to GNU-FDL. So, in summary: I think we should keep Wikinews in the public domain.
