As Geech said, pseudonyms have a long tradition. It doesn't make something less valid just because a real name isn't attached to it. If that were the case, a lot of great literary figures would be discredited just because of a pen name. And blogs work differently than real newspapers. Bruce puts his name on things because he's employed by the Daily Herald to do so. He gets paychecks and benefits. That's his compensation for putting his name on everything he writes. Not to mention the fact that I'm sure he WANTS his name on his articles in order to build his reputation and career. Bloggers don't receive that same compensation. And often, writers don't want their name attached to blogs because if they occasionally blog from work (in theory, course. No one would ever actually do such a thing) they could be fired, reprimanded, etc. And on a basic level, Ken Tremendous is a hilarious name. It simply adds to the humor of the posts, for me.
