It’s certainly exciting to see technology being used in ways that amplify and extend the impact of movement organizing. I think it’s easy, however, to misread the technology as the cause of the movement rather than as simply a tool of it.
Fire, for instance, was a society-changing tool. Its revolutionary potential, however — cooking food and thus making it more digestible, nutritious, and lasting — was only realized through its strategic use.
Some people, awed by the fire, seem to confuse it with the food.
In fact Twitter did not play that big role. The story is quite simple — young and active bloggers decided to have a flash-mob action, lighting candles and ‘mourning Moldova’ because of Communists victory, which nobody recognized due to the multiple violations before and during the campaign. They agreed on the time and place of the action through the network of Moldovan blogs (blogs aggregator blogosfera.md), and social networks like Facebook/Odnoklassniki, etc.
