i recently had a chance to pick bill casselman's brain. here's the opening blurb and link to the interview:

Bill Casselman is a veteran of print, radio and television, working for the CBC (radio & TV), Maclean's, the Vancouver Courier, among others. He's been a writer, editor, and broadcaster in various capacities. And a sometime actor. As Bill notes, "The curriculum of my vitae zigzags in a most uncool pattern." Over the past decade he's turned books on language into a cottage industry, with various texts on Canadian sayings finding a wide audience. Bill began the interview with a warning: "I give terse answers. So you'll need lots questions." He's either a liar or thankfully doesn't know the meaning of terse. Bill currently lives in Ontario, when he's not in Italy.
