The Hipihi group I started in facebook has 36 members in now, while this myspace equivalent isn't making much progress membership-wise. Why is this?

For info on Hipihi, check the company website at www.hipihi.com, in Chinese, and in English, the IdeaShape forum at http://www.ideashape.cn , and my blog at http://suezannecbaskerville.wordpress.com .
