This document discusses challenges with collaboration and harnessing collective intelligence. It notes that meetings can take many forms both physical and virtual. While collaboration has benefits of bringing great minds together, it also faces issues like different perspectives, egos, hidden agendas and groupthink. New tools like wikis, blogs and social networks may help network intelligence. It also provides examples of innovative conferences that aim to improve collaboration, such as using live demonstrations, multiple views, and audience response systems to better inform students. The goal is to move beyond traditional models and find new ways to stimulate discussion, challenge assumptions and adaptively learn.
