The mixi meetup 2010 panel discussion in Tokyo was a huge success. Details are found in Hisami’sblog (in Japanese).
All the event sessions were lively and standing room only. The point of interest was the afternoon session by mixi President Kasahara’s announcement of mixi’s new platform. He revealed that their basic policy is to become more open, as mixi’s partnership with China’s biggest social network siteRenren and Korea’s largest SNS Cyworld, as well as Japan’s Yahoo!, Rakuten, MobageTown, Hatena, among others, will implement “mixi check” features on their sites. TechWave’s Mr. Yukawa who moderated at the event has summarized this (in Japanese) here.
