I've seen some Wikia-hosted Wikies, but they don't even feel like a Wiki.
Of course it's easier than installing yourself, since you won't need to know anything about MySQL, PHP, FTP, etc., but I think people want something that has a look and feel of MarioWiki, or Wikipedia.
Plus the fact that Wikia has a huge banner at the bottom.
