“Sharing thoughts and expressions and even actions with others, possibly many others, is becoming a normal opportunity, not just for professionals and experts but for anyone who wants it. This opportunity can work on scales and over duration that were previously unimaginable. Unlike personal or communal value, public value requires not just new opportunities for old motivations; it requires governance, which is to say ways of discouraging or preventing people from wrecking either the process or the product of the group.”
