Do you want to share your tweets with your grandchildren someday? Maybe you should make a book.
AppNewser has collected five different services that will turn your Twitter feed into a book. Check it out:
Twournal: “Twournal allows you to create, buy and sell twitter books printed from your tweets. All Twournals have color covers, can include replies and photos from services such as Twitpic and Yfrog in color or black and white. You can choose a custom picture for your front cover. Select which tweets you want to start and end at. And you can add a dedication message to appear after your title.”
