Twitter to Provide Analytics Tools

Currently, there are many third-party applications out there that provide analytics to allow you to check out how influential a Twitter handle is, namely TweetGrade, Twitalyzer andTweetStats. Expected to launch by the end of 2010, Twitter will also provide users real-time analytics and data so users can find out which of their tweets are most successful, which tweets caused people to unfollow them, and who are their most influential re-tweeters.
