The first edition can be found here.
"Welcome to the NEW ARCast! ARCast is an ongoing podcast series created by the Architect Strategy Team with the goal of spawning insightful, enlightening and sometimes contentious conversations about the hottest topics in Architecture today.
Each new series will host five Architects from the community, both internal Microsoft and external folks. Panelists are free to discuss their own personal opinions about the topics and drive conversation to an open forum built for discussion and persuasion. We invite you to TUNE IN today! "
This is pretty exciting stuff as podcasts mean I can list on the commute using the trusty PDA. My only issue was that the podcast was pretty short (around 13 mins) and Architecture is a large subject! More! More! More! Please! Thanks!
EDIT: The second ARCast is now available here.
