Support for Traditional Chinese language

As title. although there is Simplified Chinese added already, however there is still a slightly difference between two languages.
Wonder will it be better to separate into two in order to get better management and support.

Hi, I can help with translating to zh-hk. However, I notice that Simplified Chinese contributor declared their language tag to zh and we request their to change the tag to zh-cn.

Hello, I would like to contribute to zh-tw, which is traditional Chinese used in Taiwan.

I totally agree with the comments above. There surely exist difference between zh-cn, zh-hk, and zh-tw.
These differences would be especially obvious in spoken language (words sometimes pronounced differently/having different meanings) and thus the language "zh" should be separated.
