Twitter buys TweetDeck application

Twitter says it has bought TweetDeck, a London-based startup that helps people read, write and organise the short messages posted on the online network.

Twitter is not giving financial terms. The San Francisco company said today in a blog post that the TweetDeck team has joined Twitter. TweetDeck will continue to be based in London and users will continue to be able to use the application.

TweetDeck lets Twitter users organise the brands, celebrities, news feeds and people they "follow" on the short messaging platform.
