I thought it would be cool if there was a survey sometime that asked people what they are studying on Skritter.
Choices could be:
Japanese
Beijing Mandarin (那兒)
Mainland Putonghua (那裡)
Taiwan Mandarin (啊)
Other: (Cantonese, Shanghainese)
Having lived in three different regions that speak the different Mandarins I have had to learn the differences between all of them. Its painful getting corrected by someone for regional differences. Each group of people also consider their Mandarin as the proper one.
