h2g2 The Hitchhiker's Guide to the Galaxy: Earth Edition

I recently finished a novel called Feed, by M. T. Anderson. Written for young adults but still a good read. It's a futuristic story about people who have a transmitter implanted in their head called the feed. It's like having the Internet in your brain. Everyone can find any information they want just by thinking about it. They can also chat to each other in their heads, and buy things.
The problem is that the feed is mostly used for advertising. Companies keep track of what everyone searches for and what they buy and what their interests are. Then the company can send personalized ads to each person based on their customer personality type.
The book is written from the standpoint of a not-very-bright young male named Titus. So his speech habits can be a bit annoying through the book. I suppose if you are a young person who talks like that anyway then it won't bother you.
