Jme, thanks for answering to my question! Tell me if you signed up for Twitter! I think its a great idea if we use Twitter in some kind of way for class like one of the assignments. Maybe we could make community like mixi and chat there.lol I like how you describe twitter as "mini mixi".
I sometimes think that those networking service site are scary. Because you can meet people who you can't see their face and talk with them, and how can you find out that they are telling the truth to you or maybe lying? I always have a fear to open my personal information to those kind of networking services. So in mixi, I open my diaries and photos to people who are my-mixi and if there's someone who I don't know applied for my-mixi to me I will definitely refuse them. I guess to protect our personal information, we have to be aware about the negative side of media.
