Best Sessions Engaged the Audience

I mainly partcipated in the Strategy and Business Model track and I have to say the best sessions were interactive. For example; Soren Stamer, CoreMedia provided such an extreme real-world example it engaged the audience into a discusion. Andrei Nabergoj, New Europe Online, had a small group attending Thursday morning, but had everyone introduce themselves and state why they are attending his session that lead to a very interactive session. Lee Bryant also kept us from chasing our tails on a tool discussion in the Enterprise 2.0 session. Stating that it is really about organizational change and adoption, not tools! That open a very informative discussion... These are a few examples....I wish I could point too more....
