Maybe Chinese is indeed special, but generally splitting and fragmenting can be very bad. For example German wikipedia -- english content is in most cases much better and easier to understand than german content. For computer programming -- one of the few good german books I read was from N. Wirth 30 years ago, I am not aware of other really good CS books in german languages. This is even more true for books about physics. My only good experience with native language groups was in the past with Latex and electronics in usenet, something like de.lang.latex and de.sci.electronics. Experience was good, because these communities contained some german speaking experts that time. But Araq and mratsim seems to speak Chinese not that well, so some other chinese speaking experts would be needed.
Generally my impression is that native language groups are fine for kids and very old people. But today learning english is even more important than learning C language, and my feeling is that Chinese people with a scientific background are very good in English.
