Unlike many other celebrities, the 'Leaves of Grass' actor has never written an internet blog because he hates the idea of people cyber stalking him.
The 40-year-old star explained: "I haven't personally really engaged in a lot of this new kind of social networking stuff like Twitter or Facebook or MySpace.
"I mean, the notion of people following what I am doing every day is like torture for me. It's absolutely the last thing that I'm looking for. It seems to me to be really just about social chatter."
Despite his web worries, Edward agreed to sign up to Twitter to help raise money for his favourite charity, the Maasai Wilderness Conservation Trust.
He added to Parade magazine: "It's a good example of a way that you can turn that platform into something where you actually can accomplish something good.
"It's my first attempt. We're putting our running training log on Twitter. You can see can see pictures too on the site there."
The trust conserves the wildlife and culture of the Maasai tribe of Kenya, Africa.
