At the risk of sounding pedestrian, I'll be completely honest: the first thing I do in the morning is check Google News, partially because it seems sort of random and unbiased and partially because I tend to stay in hotels that don't necessarily have the fastest Internet connections.
At the same time, I think books create a sort of network in the reader's mind, with one book reinforcing another. Some books form relationships. Other books stand in opposition. No two writers or readers have the same pattern of interaction.
