Let's get one thing straight: This is utter, blatant satire. SATIRE. That means that the authors are trying to poke fun at the foundation that literature is based on. Since I'm in high school, I've read quite a few of the classics and I must say that I really did dislike some of them. The authors are geniuses to evoke laughter as well as horror as well as a sense of brilliance for doing this. I'm not saying that this book will be a replacement for any of the books it degrades, but it's a fine way to supplement your knowledge of classic literature in a humorous (if vulgar) fashion.
I can imagine that the audience most offended by this book would be those that have enjoyed these classics for decades/ does not know how twitter works. I've shown this to a few English teachers and they have laughed at seeing their favorites being deconstructed in a mere 1400 or so characters (most books being 10-20 tweets, 140 characters max.)
Just a quick complaint: The book does go into vulgar territory, so much that one could deduce that a couple of college students wrote this as a way to pass time. With that said, carry an open mind, read a "twitterized" passage and ROFL until morning.
While it may be an indication that conventional learning has gone the way of the dodo, it's also a refreshing take on centuries of books.
