TweetDeck is a social media dashboard application for management of Twitter accounts. Originally an independent app, TweetDeck was subsequently acquired by Twitter Inc. and integrated into Twitter's interface.
The most powerful Twitter tool for real-time tracking, organizing, and engagement. Reach your audiences and discover the best of Twitter.
TweetDeck users can tweet, reply, retweet, favorite, send Direct Messages and manage and monitor multiple accounts and streams, all in one single interface. … When sending tweets, TweetDeck uses Twitter’s own URL shortener so that any link pasted into a tweet will be automatically reduced to 23 characters.
