Extras (Uglies Series)
This follow-up book to the Uglies series is a world imagined where only Twitter and blogging matters. Okay, Twitter isn't actually mentioned but the central premise is that only "face rank" matters in an economy driven entirely by feed popularity. Reputation rank is determined real time based on how many people "kick" (retweet) your updates. The better your face rank, the more privileges you get. Thoroughly entertaining and up to the minute. I suspect that even if you don't normally read science fiction you'll enjoy this book if you blog or are addicted to Twitter.
