Fork?
I think a fork would be a great idea. All the material in Wikipedia is GFDL:
http://en.wikipedia.org/wiki/Wikipedia:About#Trademarks_and_copyrights
That would be awesome if somebody cloned the contents and used it to start up a competing site, except with an attempt to make less dysfunctional rules for differences of opinion among editors.
I find those "citation needed" thingies extremely irritating. It feels so much like a pre-emptive justification for removing material you don't like.
