Interactivity has the virtue of democracy, conferring upon everyone with access to a computer the right and opportunity to be heard, but it's also saddled with democracy's vice — a tendency to assume that everyone who has a right to be heard has something to say that's worth hearing.
Never has America been more alone in spreading democracy's promise. [...] It is the last country with a mission, a mandate and a dream, as old as its founders. All of this may be dangerous, even delusional, but it is also unavoidable. It is impossible to think of America without these properties of self-belief.
