Ashton Kutcher has given up Tweeting by himself.

The Two and a Half Men actor is one of the most popular people on social networking site Twitter with over eight million followers, but after making an ill-advised comment seemingly defending NFL coach Joe Paterno - who was fired for allegedly covering up child abuse by his assistant coach - he stopped tweeting. "As of immediately I will stop tweeting until I find a way to properly manage this feed. I feel awful about this error," he wrote last night.

Today, Ashton has come up with a solution, and from now on his thoughts will be filtered through his media team. "Up until today I have posted virtually every one of my tweets on my own, but clearly the platform has become too big to be managed by a single individual. A collection of over 8 million followers is not to be taken for granted. I'm going to turn the management of the feed over to my team at Katalyst Media to ensure the quality of it's content. My sincere apologies to anyone who I have offended. It was a mistake that I don't think will happen again," he wrote in a blog post.

Ashton also clarified his controversial tweet, saying he had merely seen that Joe had been fired, and incorrectly presumed it was because of his age, rather than other controversies.
