Ah to wake up to find out I'm on the front page of Channel9. :)
I did a simultaneous video/podcast with Charles Torre about a month ago and it was posted last night.
Now, just to be clear, I know I'm not the only Microsoft podcaster. The "Microsoft Podcasting World HQ" was just a blatant attempt at promotion to get people to watch and listen.
A list of Microsoft podcasters are: (and I'm sure there are more)
Larry Hryb http://www.majornelson.com
Stephen Lamb http://blogs.msdn.com/steve_lamb
John Howard http://blogs.msdn.com/jhoward
Tiernan O'Toole http://feeds.feedburner.com/lotas
Eileen Brown http://blogs.msdn.com/eileen_brown/archive/2004/12/09/278983.aspx
Steve Lacey http://www.steve-lacey.com
If you work at Microsoft and podcast, leave a comment or drop me an email (see link in the upper left hand corner) and I'll update the list.
