Ashton Kutcher on Twitter -- I Can No Longer Think for Myself

Ashton Kutcher doesn't trust himself with his own thoughts ... claiming his ignorant Twitter defense of Joe Paterno has made him realize that he isn't qualified to speak to 8 million people.

Kutcher just posted a long-winded message on his blog -- explaining that he has decided to turn over control of his Twitter account to his management team -- which will now filter Ashton's stream of uninformed thoughts before they are unleashed on the masses.

Kutcher writes, "Up until today I have posted virtually everyone of my tweets on my own, but clearly the platform has become to big to be managed by a single individual."

He continued, "While I will continue to express myself through @Aplusk 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."
