It might not be a bad idea for us to so honor the Iranian people now.
It is a tiny, useless gesture. But I think it's worth doing something small, public, and somewhat collective to show that the American public -- the public elsewhere, for that matter -- gives a shit, and it's either that or go onto the roof and shout "God is great," which doesn't have the same patriotic connotations here as it does there.
I am on a business trip in the middle of nowhere and am the least socially networked person in the world, so I am very ill-placed to start anything. But those who are better abled than I and are watching events in Iran with great concern might consider giving this a shot.
