So.. you mean doing a experiment for using different name? i have a experience for this. I am a HongKongese, and you know we have chinese name and english nick name. Once I introduce my English nick name and Chinese name to different person, and it is interesting that when two of them talk about me and they don't know which refering the same person. It's interesting.
Yes I am familiar with that as my friends fron Hong Kong and Guangzhou all had English nicknames. That is the only place I have ever heard that being so common
