Social network

I found Classroom 2.0 useful and interesting because there are lots of conversations going on. Especially, in terms of discussion, LIVE conversations in the network is a good place to visit. Because there are saved conversations, I can take my time to read them and find information I need, and because there are also links, I can get further infromation directly. For example, using wiki in classroom is a new idea to me and I donn't have clear ideas what is wiki, how I can create it, what I can do with it, etc. In the LIVE conversations, there is a discussion about wiki. In addition to getting information I want to know, I found people who share the same or similar questions with me, so I feel fine becasuse I'm not the only one who are not familiar with the current technology. I'd like to keep track of the social network.
