I had a great conversation with Dvortygirl today. We discussed many of the things that have to do with WiktionaryZ. We discussed locales and that the locales you use in computing do not match linguistic locales. Dvortygirl knew this resource where there used to be a dialect survey where Americans were asked some 50 questions to determine how the usage differs from place to place.
When people want to do this kind of research, it makes sense to have a place for it in WiktionaryZ as well. It dawned on me that I have not really considered many of the User Interface questions that will come up. Then again some things are obvious. People will not only want to select the language that they see. There will be a need for a portal page for each language. This could be the kernel for a portal page for the English language (from the Dutch Wiktionary).
With starter portals like this, it can be expanded in many ways. Many internal (to the Wikimedia Foundation) and external resources links can be added and give users a rich experience. The Main page of WiktionaryZ would therefore be similar to the http://wiktionary.org website particularly to point people in the right direction.
