For the most part, the Etech conference was made up of two groups: the graybeards and the baldies (alternatively the t-shirt brigade). Although there was an unfortunate disconnect between the two (a generational thing?), both are trying to change the world while having as much fun as they can doing it. An important goal for the next conference: combine the optimism of the baldies with the experience of the graybeards. This will create both sparks and new ideas.
