Harold, this is a great example of where I believe thof web2.0 will bring us. When people ask me why these tools are making a difference, the opportunity for community and learning are what I mention most. Here we are individually and collectively reflecting on the model, our own habits, each others' comments and comments on comments. I am less dependant on RSS, a dedicated user of del.icio.us and the host of numerous collaborative environments where some lively discussions and chats are hosted. I have started to use wikis for co-writing. So I would add a loop back from to to indicate that this is an iterative process.
