All in all, I'm pretty happy with how the Ken Jennings dissed! thread that I put up on MetaFilter turned out: 41 comments, basically positive. Even had a comment from someone who'd met Ken in RL, back in his pre-Jeopardy-celebrity quiz bowl days. Maybe I turned some more people on to Ken. At any rate, I feel I've done my duty to geekdom.
While I'm at it, I may as well point you to the original MeFi Ken Jennings blog post.
And, since I've already jumped the shark on all of this Ken-stuff, I might as well link his very informative page on Wikipedia.
