According to a report by The Wall Street Journal, Twitter is in “advanced talks” to purchase TweetDeck β the popular desktop and mobile third-party Twitter client. The deal could be worth as much as $50 million, although neither party has commented on the possible acquisition. TweetDeck, based in the U.K, has 15 employees on its payroll. Twitter could use the acquisition to immediately offer a “native” Twitter client in the PC desktop space, especially if it has plans to begin targeting enterprise Twitter users. Although TweetDeck’s engineers have certainly proven that they have the developing chops to compete in the mobile space, too.
