Back in January Apple created an official Twitter account for its App Store. @AppStore allows users who follow it to get the latest on App Store news and deals. 745 tweets later, Apple has decided to open up another Twitter account. @iBookstore offers followers "official updates from the U.S. iBookstore from Apple, including featured books, exclusive offers, and more." The account went live this afternoon and currently has three tweets and a little over 2000 followers.
