Serena Williams and Andy Murray are leading the charge of top-level players who are using their Twitter accounts as means for communicating with their fans.

Last week, Williams created a stir when one of her Tweets complained about a ‘new rule’ in the locker room regarding no food. Wimbledon officials went on the address the situation, but it marked one of the first times in the tennis world that Twitter has been used a means of unofficial communication, giving the social networking site even more power on the web.

TennisTweets.com is a free online service that offers Twitter users and non-users alike to follow professional tennis players. Players such as Andy Roddick, Amer Delic, Sabine Lisicki and Laura Robson are constant Tweeters, while others like retired commentator Jim Courier, Murphy Jensen and Justin Gimblestob also use the service.

The Twitter craze has reached such a height on the pro tour that even the ultra-private, introverted Venus Williams has signed up this past weekend. Her first Tweet: “Just won my 2nd round singles match and 1st round doubles match at Wimbledon!”

And speaking of Wimbledon, the tournament itself is the most addicted of all, Tweeting match scores, updating fans on weather, inside gossip and the like. Oh, and don’t forget to add TSF to your Twitter after you add all those A-List tennis folks. Can’t forget the little Tweeters in life!  

But who’s most popular of all in the tennis-Tweeting world? That would be Serena, of course, with over 487,000 followers.
