What are the motifs in Feed by M.T. Anderson?

Self expression is a recurring idea. As the novel begins, Titus is a normal teenager. The feed controls him as it does his friends. He does immature things such as horseplay and giving into the whims of his unintelligent friends. He thinks everything is boring, even trips to the moon and Mars. He is a vapid character who cannot think for himself. Instead, he lets the feed think for him. However, when he meets Violet, who is a traditionalist, he begins to think. Violet makes him think about things he otherwise never would. Instead of the feed choosing everything for him, he starts to go on a self-journey. He realizes there is more to life than the feed due to Violet. She can read, write and sew—all things a normal human without a feed can do. He is fascinated by this and delves into her world.
