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.
Kaishu let me know on the wiki that this statement was misleading, so here is a clarification. There are several linguistic groups on Taiwan, including:
* Speakers of Ho-lo-oe * Speakers of Mandarin * Speakers of aboriginal languages and other dialects of Chinese
Of the speakers of Ho-lo-oe, most write using what we would call Traditional Chinese, a script which historically was promoted throughout East Asia by Chinese conquest and influence. A small minority of Ho-lo-oe speakers promote the use of latin-based orthographies, which follow phonetically from the spoken language. Such orthographies are referred to as "Peh-oe-ji", which means vernacular. The point I was trying to make with the quoted paragraph was that Ho-lo-oe speakers contribute to both zh.wikipedia.org and minnan.wikipedia.org.
