Ken Jennings was a kind of hero of mine when I was on his massive winning streak because I thought he demonstrated that the ability to think was different from the ability to memorize. He treated the whole game in a tongue and cheek kind of way, and in the end, took home $2.5 million. Not bad.
Yesterday, on his blog, he slammed Jeopardy! for among other things, the exclamation point in the name of the show. (He also has some interesting points to make about a show of that nature.) Very tongue-in-cheek and very amusing.
