POJ finishes at bottom. Only 100,000 literate users

[MiLi]

The majority of native Southern Min speakers in Taiwan are unfamiliar
with POJ or any other writing system for the language, commonly
asserting that "Taiwanese has no writing", or considering romanization
as the "low" form of writing, in contrast with the "high" form
(Chinese characters). For those who are introduced to POJ alongside
Han-lo and completely Chinese character-based systems, a clear
preference has been shown for all-character systems, with all-
romanization systems finishing at the bottom of the preference list,
likely because of the preexisting familiarity of readers with Chinese
characters.

POJ remains the Taiwanese orthography with the richest inventory of
written work, including dictionaries, textbooks, literature, and other
publications in many areas. A 1999 estimate put the number of
literate POJ users at around 100,000, and secular organizations have
been formed to promote the use of romanization among Taiwanese
speakers.
