In The Office finale, Creed mentioned that he had a blog. He gave an address a little too fast, so I figured it was probably just a plot point. But then, NBC does like to get it's web stuff out there (remember http://www.thetoddtime.com/ ?). Then Ryan said it was a hoax that he did to Creed because the stuff he wanted to write was too out there, so then I knew it was just a plot point.
But wait-- Creed really does have a blog on nbc.com. My friend, Brian, found it and sent me the link. Check it out, it's great. And it ties into the beach party episode. It also doesn't have any video (unlike thetoddtime.com), so even Old Man can enjoy:
