For Jim Gilliam, the founder of NationBuilder, community is everything. When he needed a double lung transplant, Gilliam turned to the Internet and to his online community to make it happen. He's organized political campaigns, made documentary films, and built his company NationBuilder by tapping into the power that large scale communities on the internet provide. Community at internet scale is a deep reservoir of people, ideas and yes, money, that Gilliam believes changes how we do almost everything - and makes almost anything possible.
