Being one myself I noticed that there are not many Chinese bloggers on WP. Almost all my Chinese friends blog at MSN Live Spaces, which is about the #1 blogging site in China (and growing fast). That's probably why it made Live Spaces the largest blogging service. Of course, they all blog in Chinese.
Last week a friend of mine in Beijing just told me that she couldn't get to my blog at WP no matter how she tried. My guess is wordpress.com domain is being blocked by the Great firewall of China. Perhaps that explains why so few Chinese bloggers are on here.
I blog in English but am curious to find out about the Chinese bloggers here, whether you do it in Chinese or English.
