It is too soon to know or to say how the situation in Iran will turn out, but there are lessons in this for our own country, for a democratic system more fragile than we at times like to believe.

And the other is the lesson that citizen journalism is a way for the people to hold on to freedom of the press, even in times of oppression. In a turn of phrase that seems to be cropping up everywhere, the revolution may not be televised…but it very well could be Twittered.
