About a month ago, Shizhao requested that the wiki at minnan.wikipedia.org be moved to poj.wikipedia.org, because the writing there is Taiwanese, and not representative of Min Nan as a whole:

Kaishu Tai ridiculed the POJ term as "meaningless", and requested that the wiki be moved to zh-min-nan.wikipedia.org instead.

I didn't know who to believe, and although I made some attempt to make sense out of it, the end result was the status quo.
Just today, I did some reading of my own on the subject. The best reference I found was this:
http://www.de-han.org/taiwan/chuliau/pehoeji-v.pdf
Other information sources are: http://203.64.42.21/iug/ungian/POJ/siausit/2002/2002POJGTH/lunbun%5CK2-kloet... http://en.wikipedia.org/wiki/Taiwanese_%28linguistics%29
Contrary to what Shizhao said, it seems that the Peh-oe-ji orthography, as seen on minnan.wikipedia.org, is not even representative of Taiwanese, let alone Min Nan. In fact it is only used by a small minority. Now I have every respect for the goals of those who promote Peh-oe-ji, but I don't think Wikipedia should assign subdomains which support one political viewpoint over another.
Currently the predominant form of writing in Taiwan is "Traditional Chinese", given the code zh-tw. Writing of this form is commonly used on zh.wikipedia.org. The Taiwanese people who write in zh.wikipedia.org speak the exact same language as those who write on minnan.wikipedia.org. That language is a form of Min Nan, referred to in Taiwan as Ho-lo-oe.
Based on the information I have now, I would like to move minnan.wikipedia.org to peh-oe-ji.wikipedia.org. I'm expecting objections to this from the users of that wiki, who seem to be keen promoters of the Peh-oe-ji orthography. All the same, I'd like to hear any comments or objections anyone has.
