LOS ANGELES  - Celebrities may want to resist the urge to send a stream of consciousness on Twitter in the new year after so many of them tweeted their way into trouble on everything from boxer briefs to breast-feeding in 2011.

NASCAR driver Kasey Kahne became the latest celebrity to blunder on Twitter, when he had to apologise for a tweet critical of public breast-feeding.

But Kahne has been far from alone in discovering Twitter’s pitfalls. The year 2011 saw US congressman Anthony Weiner resign in a scandal that began with an errant tweet, and the musings of Hollywood stars such as the tech-savvy Ashton Kutcher and comic Gilbert Gottfried generated public controversy.

As a result of those and other scandals, 2011 may be seen as a turning point when more celebrities and politicians saw the dangers of Twitter and quit sending unfiltered messages, pop culture experts said. Handlers of celebrities are likely to play a larger role in managing the stars’ Twitter accounts.
