Social Software for IE

I am going to use Mixi, one of the SNS sites in Japan, for my IE homepage.

＜Explanation from Wikipedia＞
Users can send and receive messages, write in a diary, read and comment on others' diaries, organize and join communities and invite their friends.There are more than 4 million members and 490,000 communities. (May 2006)
・A community is a place for people to share their opinions through an online forum and a way to express tastes and hobbies.
・A footprint ashiato (足あと, ashiato) is a function that allows a user to see who has visited their page.
・mixi is an invitation-only service, meaning that one can only join via an invitation from a current member of the service. However, once invited, membership is free and open to anyone over 18.
・The word mixi is a combination of mix and I, referring to the idea that the user, "I", "mixes" with other users through the service.
