I like the idea of using the Nupedia approval process to bless Wikipedia articles.
Only one little concern: a link on every page "Submit to Nupedia" seems overkill. Nupedia editors will get annoyed by too many, and repeated, submissions, and users will be confused what this is all about. Why not restrict the submitting action only to logged in users, and then only from the edit-page? That way, the unwashed masses never have to deal with it.
