My PhD supervisor, Wayne Kelly, is on Channel 9! He's giving an update on the Ruby.NET project - http://channel9.msdn.com/ShowPost.aspx?PostID=295197 There were some other interviews on the day so I expect we'll see something from Joel, John and Joseph soon.
BTW, the room he's in for this interview will be populated this Friday by the poor souls who decide to listen to my PhD defense.
