Twitter seems to be in no mood to slow down its offensive against third-party app developers. The latest move is dropping name of the source application from tweets on its web interface which means that any tweet from an application such as TweetDeck, Tweet-bot, or Seesmic will not the accompany the “via” field which carried the name of the application that was used to post that particular tweet.

” Nearly eighteen months ago, we gave developers guidance that they should not build client apps that mimic or reproduce the mainstream Twitter consumer client experience. “, said Twitter in the blog, which announced the new API rules.
