What we can say for certain is this: from Occupy Wall Street and YCombinator to co-living in San Francisco and co-housing in the UK, something important is happening. People are meeting like minds in the cloud and traveling to meet each other offline, in the process building community — and tools for community — where none existed before. Those cloud networks where people poke each other, share photos, and find their missing communities are beginning to catalyze waves of physical migration, beginning to reorganize the world.
