Distributed as in non centralized. Many people feel like there is nothing they can do to contribute to meaningful change, especially with how spread out Americans are, but surely there has got to be something.
Using the trend of blocking traffic as an example, I think a coordinated effort to not just block a highway in one city, but to block state routes and other arteries in many places would be more effective. Instead of one city having bad traffic for a day, it would be many towns and it would be harder to dismiss as a local problem if people across the states are engaging.
Keep in mind that decentralized and distributed should not be confused for individualist. A group of three people can do a whole lot more than an individual.
