Yes, the Dutch wiki needs work... lot of it, and rather than complaining about it here, go fix one typo, or one page, or one section..... and before you know it, it will be just as good as all the rest.
If you want a non Brazilian Portuguese wiki, start a project, and make it happen! That's what the Brazilians did!
