@FMarquardtGroup - encounter over dinner that one may end up not being invited to or for a coffee conversation that may not happen because the person one hoped to talk to was in side meetings all the time? Instead, we may want a lot less meetings but meetings that are focussed on the core of why we meet in person - unconferences (which an amazing facilitator once described as "structured week-long coffee break") are perfect for that or any other structures than encourage interaction.
