I don't think he'd waste his time on the internet, just like he didn't (as far as we know) waste his time writing letters to people.

I think he would be out healing people and casting out the demons that cause all of this mess in the first place.

But I'm not him, so I don't really know. I'm under the impression that when he returns, he won't be as nice and accommodating to the rulers of the world as he was last time.
