As always, the operating question should be "do the pages fit the purpose of the wiki"?
They certainly don't fit the purpose of the Main namespace, so I think it's a no-brainer that any of the cutlery pages that are in Main need to move out.
I suppose, as meta-commentary on the site, a case can be made for the Darthwiki namespace, if there's a belief the pages belong on the wiki side at all...
...but perhaps they don't.
Wouldn't they make more sense as forums? The pages don't catalog anything (other than troper names), and really wouldn't be missed from the wiki — but there's always a value in community, and where better for community than the forums? I'd open up a "Community" section under Just For Fun in the forums, give each cutlery group a thread, and let them have their fun. What would be natter on a wiki page becomes ordinary discussion on a forum, right?
I guess what I'm saying is that instead of trying to make the community (cutlery) groups fit the wiki, put them where they fit better.
I am not a mod, and I don't play one on TV.
