Someone asked me recently what the point of Twitter was. I made a joke about how following comedians is the only reason to join.
I'd like to change my answer.
The election in Iran is the point of Twitter: skirting around official lock-downs, fighting back against voter fraud, organizing protests in not only a town, but a country, a continent, the world.
Social media can seem silly and self-involved. But when we all need a fast, efficient means to communicate information that is vitally important, that media's built-in ability to do so suddenly becomes the thread that ties everyone together.
