let us sum up basic fact, pro and con we had discussed in a NPOV manner. ==basic fact== *The same language: Chinese. *Two writing systems: TC & SC. *Chinese Wikipedia now mix TC and SC together. *Chinese Wikipedia community now have a consensus on unity. *SC artical vs TC artical at Chinese Wikipedia is about 10:1. *a unified solution is workable, although it is also acknowledged that there are significant challenges. *Someone tried to develop a solution for the differences in vocabulary among Taiwan, Hong Kong, Mainland, Singapore and Macau, the basic idea of the solution works. *there are huge and permanent implications of splitting up the two ==pros of a single version== *it makes the most sense from a language point of view *it makes the most sense from the point of view of having a top quality NPOV resource. *zh would work towards a traditional-simplified solution. *The advantage of a technical fix to the character problem to have one version is that the problems don't grow with time *The problem set of making two characters sets work isn't a fast moving target. ==cons of a single version== *The SC UI is uncomfortable and scared away some of the TC users. *It is difficult for the TC users to look up some material such as names of places and people from traditional. ==pros of two seperate version== *attract more TC users. *there is a larger corpus of texts, many of them fundamental texts, which exist as originals in traditional characters. ==cons of two seperate version== *low quality on NPOV. *a technical fix to the character problem to diverged versions grow with time. *keeping up with two sets of wikipedians is a fast moving target.
