demo = fun

Didn't know I would like demo so much. This 2-hour session is the most fun I had in any class. Free-style presentation topic makes the knowledge pool much bigger. 10-min constraint makes people highlight the most interesting and important part of the topic. This makes the 'interest-matching' process efficient. I'm thinking maybe in a team, we can do that too, with a bit relaxed time constraint. That would be fun.
