Twitter has launched a free app for the iPad. When you tap on a tweet with the app, a content pane will open that displays any linked content from the tweet, including web pages, profile information, hashtag searches and similar users. You can pinch on a tweet to quickly unfold related information and actions. You can also use two fingers to drag on a tweet and reveal replies. You can preview Twitter's iPad app here on iTunes.
Digits reports that Twitter's iPad app was developed internally by Loren Brichter, the designer of Tweetie, Twitter's official iPhone app.
