RIP Alex Trebek
He announced his cancer diagnosis quite a while ago, so this didn't actually come as much of a surprise. He had the rare gift of sounding extremely intelligent without appearing condescending or pedantic, and always seemed to be genuinely interested in the person with whom he was conversing, whether it was a contestant or someone interviewing him. I haven't watched Jeopardy in years, but I feel like the world's a little less bright with the loss of the light of his presence in our society.
