I should add, Aaron Schwartz really understood these things.

He would identify rational people, have the talk, and then ask them a question, rather than force acceptance. The outcome is they, themselves come to acceptance, and when they do, Aaron was there to join in common, worthy cause.

By doing this, and avoiding noise and irrationality as well as core value differences, he built mindshare and motivation to act, both far more potent than just being right is.

Miss that guy. Big.
