Common Name: mixi
Niche: Japan, 18+ social networking website
What they say about themselves: I don’t know, I can’t read Japanese, and you can only get access to the site if you are invited by another memeber.
What I say about mixi: They must be doing something right since they have an 80% share of the Japanese social media networking market and have grown from approximately 10,000 memebers in 2004 to nearly 20 Million in 2008. I’ll add that I like the idea of viral networking. Rather than “blogs” mixi calls it personal postings “diaries” (even the Japanese interface uses this word). Mixi is free to use and designed for the 18+ Japanese social networking market.
