Tweetbook is simple yet very useful. You can now read, share or backup all your Twitter updates (tweets) as a single PDF file called tweetbook.
You can generate your tweekbook out off your tweets, including replies as well as your favorites tweets if any. On top of that, you create a XML backup besides PDF.
You can share your tweetbook via Scribd and this is done automatically via the Tweetbook app. Here is my tweetbook: http://tweetbook.in/v/17521043
