Cybespace = Pretty context for Learning!?

In Bloch's article, Second Language Cyberspace Rhetoric, he cites Sproull and Kiesler's argumentation: electronic communication alow for interaction based on shared interest and not physical proximity, thus allowing members of an Internet community to be simultaneously linked and buffered from one another. This argumentation is used to support the concept, which is "safe house". I agree with this argumentation. Cyber interaction grows rapidly up nowadays. There must be some special reasons for it. Except the convenience, it provides a very important and obvius advantage, which is no-face-to-face interaction. Human beings are funnily strange. We must live with others. But we are ffraid to interact with others. And the phenomenon is getting apparent--there must be some psychological reasons for it. Therefore, cyber interaction successfully wins people's hearts. Take my own experience for example. To some degree, I like cyber interaction. It's because that the invisible wall which the Internet builds up provides me a space of buffer. The advantage of buffer demonstrates its good in the case that I am interacting with foreigners in English via the Internet. Usually, I am a coward to talk with others face to face in nglish because I cannot get what others exactly say. And it makes me feel difficult to respond to others. And moreover, I once gave back a wrong or strange response. It's so embarrassing. The Internet eases me well, however. Before I giving response, I can spend a little bit time using some tools to understand what others say. And then give back my response. Though it takes some time, I still enjoy in it. As long as I can understand what others talk, I would be much willing to keep communicating with others.

In Bloch's argumentation, he stands for that cyberspace would be a very good context for Chinese L2 writers to improve the skill on writing in argumentary and critical thinking. This is the point which I am suspicious of. Would it really be good for improving writing skill? In my opinion, the cyber learning just give learners a sense of security. Writers are not affraid of writing too much. On the contrary, they are courageous to write. It doesn't provide any very good way to help learners wrtie good in formal. It's because of the lack of guide. In other words which would be more clear, no direction leads writers into a correct and formal writing. Writers in cyberspace follow only what they want to write. They don't usually think about how to make their articles better. But when they are in class, teachers would give them comments immediately.
