One thing I've decided to this weekend was that I wouldn't have "dead times", so everytime when the presentations were not that interesting, or if I thought I could listen to it and do something at the same time I was with my laptop managing some stuff or coding on SLTalker, my project that aimed to create a talker interface for Second Life.
