"Twitter was intended to be a way for vacant, self-absorbed egotists to share their most banal and idiotic thoughts with anyone pathetic enough to read them," said a visibly confused Dorsey, claiming that Twitter is at its most powerful when it makes an already attention-starved populace even more needy for constant affirmation. "When I heard how Iranians were using my beloved creation for their own means—such as organizing a political movement and informing the outside world of the actions of a repressive regime—I couldn't believe they'd ruined something so beautiful, simple, and absolutely pointless."
