I have noticed that editorials are now posted regularly on the German Wikinews, at http://de.wikinews.org/ - these are basically regular pages signed by a single user. Examples:
http://de.wikinews.org/wiki/Kommentar:_Chinas_Langer_Marsch_ins_All http://de.wikinews.org/wiki/Kommentar:_Der_Bundeskanzler_bewegt_sich_mit_der...
I do think we should let the German experiment unfold for a bit, but I also think people should be aware that it is happening, due to NPOV concerns about the issue.
As an alternative to editorials, I have suggested moderated debates, whose transcripts would be edited, summarized and published on the wiki: http://en.wikinews.org/wiki/Wikinews:Debates
I believe this model allows us - by having the topics decided by the community - to avoid the specter of the "In defense of white power" type editorial, and to present opinions from notable individuals in an NPOV manner instead.
Meanwhile, editorials in the user namespace are also being debated again on the English edition: http://en.wikinews.org/wiki/Wikinews:Water_cooler#Wikinews_Editorials
Which solution, if any, do you think might be best?
Best,
Erik
