It was a very interesting lecture I have ever attended, the way to be taught as very different from the others. In the lecture, there was no slide or clips, but all verbalized. Then, the lecturer did not really prepare at all but passed the question sheet through to let us asked the questions.

I was very impressed that the copyright issues are very important in the network that I have never thought of that. Maybe posting a link up to my own blog is infringing copyrights. And the lecture had pretty much time to cover this topic, I think it is the best part of the lecture to remind me to avoid being sued because of copyright issues.
