Today is the 100th birthday of Marshall McLuhan, the Canadian scholar who forever changed the way we think about media and their effects on the human psyche.

Last week I sat down for a conversation with Len Edgerly, host of “The Kindle Chronicles,” on what McLuhan would think about the Kindle, the iPad, and what effects e-readers would have on our perception of text, reading and linearity. The interview grew out of my recent review of Douglas Coupland’s McLuhan biography for Nieman Reports.

Len and I had great fun, and I hope you’ll have a chance to give it a listen.
