I am an Englishman who lives on the beautiful island of Hainan just off the Chinese mainland. I speak (and read and write :) ) English and Chinese and have the following interests in the OSM project (for which I use JOSM):
-Improving the integration between OSM and Wikipedia (through adding Wikipedia=* tags
-Improving the bilingual (i.e. English / Chinese) naming on PRC maps
-...er, anything else that I come across.
