-- Yesterday I phoned in a conference talk as Dean Dad. Scott Jaschik did a panel at a regional conference of community college leaders, mostly presidents, discussing changes in the venues for public discourse on higher ed. He spoke primarily about journalism and the blogosphere, and I addressed the group via speakerphone as a sort of Exhibit A. There's something strange about doing a conference talk when you can't see the audience. It reminded me a little of my radio days, except that I never went that long uninterrupted on the air.
