I am in charge of CSDN development team. We don't have a plan to make an English version yet as for now our focus is still on local open source community setup. Maybe one day when the situation is mature enough...
+1. Too often organisations like CSDN, 51CTO, etc believe that the Chinese market is 'totally' different and therefore needs a different approach/method. They still need to realize it is not the message itself, but 'how' you tell the message.
Side note: I have been closely involved in the Chinese Fedora community; assisting and streamlining procedures within the community and getting the community members closer aligned with the project and project goals. As a project we actually haven't treated Asia or China any different from other regions, such as South America, Europe, etc.
China market is not totally different of course, which is self-explanatory that we have similar services with Github, Stackoverflow, Wordpress and Hacker News.
However, it is still different, sometimes very different in details and implementation. And the difference needs time and efforts to eliminate.
