Hi, I'm a Korean twitterer. There are two main social network services in Korea.
Blog and cyworld. Most of Korean people have been using them. Recently, I could use twitter at first by my friend's introduction. It's cool, simple and very easy to use but not yet accustomed to using them. So I suggest you that the synchronization module of Blog(and cyworld..) and twitter. If someone write something on their blog, the follower can see the part of its writing on twitter. If this is possible, twitter may widen market share in Korea as a new type of simple social networking service. Please refer to my idea, and if you have any futher question or any idea please let me know. Good Luck,
