Twitter seeks to buy TweetDeck

Twitter, which allows people to send 140-character text messages, or Tweets, to groups of so-called followers, is one of the Webs most popular social networking services. Twitters offer for TweetDeck is between $40 million and $50 million depending on how Twitters shares are valued. The deal would give Twitter an application that has won praise among sophisticated users for its slick interface and enhanced capabilities, while closing out a potential threat to Twitters fast-growing service.The cash and stock deal could close in less than ten days and would represent one of five-year-old Twitters largest acquisitions to date.
