For CLR wonks (and all others interested in the whys and hows of the .Net Framework), Jim Miller, best known as a CLR Architect and author of the book The Common Language Infrastructure Annotated Standard (a great book, by the way, if you want to read the ECMA specs in book form that Jim Miller wrote, along with annotations), has been interviewed on The ServerSide.NET by Ted Neward. See the interview here.
NOTE: A transcript is available as well if you are not able to view the video.
